SN74HC595N DIP-16 Shift Registers and Logic Kits

SN74HC595N through-hole shift registers and related selections

Shop SN74HC595N / 74HC595N serial-in, parallel-out logic IC lots, selected 74HC-series assortments and multi-model listings that include an SN74HC595N choice. This collection is centered on the bare through-hole shift-register IC, but many product titles list several alternative chips. The option you select, not every model named in the headline, determines what is ordered. Other models in these mixed listings remain here for browsing; they are not advertised as equivalent substitutes.

Understand the device before choosing a lot

The 74HC595 function is an eight-bit serial-input shift register followed by a separate eight-bit output storage register with three-state parallel outputs. A serial clock advances incoming data; the storage clock transfers the shifted pattern to the outputs, allowing the previous output pattern to remain in place while new bits are loaded when the circuit is operated appropriately. A serial output allows compatible devices to be chained for more output channels. Output enable can place the parallel outputs in a high-impedance state; it is not the same as reset or storage clock. Confirm clock edges, reset behavior, output-enable polarity and cascade timing in the exact manufacturer's datasheet rather than copying an unspecified seller diagram.

SN74HC595N listings here predominantly describe a DIP-16 or 16-PDIP through-hole chip. The suffix and package matter: a DIP-16 part is physically different from a SOP-16 surface-mount 74HC595D selection, even though both may implement the 595 function. One product explicitly offers 74HC595N DIP16 and 74HC595D SOP16 as different Color choices, with a second field called Voltage actually setting 20, 50, 100 or 200 pieces. Do not interpret that quantity field as an electrical rating. Conversely, two bare-chip product titles say 'DIP-14' while naming SN74HC595N; that is a conflicting package claim, not a verified 14-pin 595. Confirm the device marking, 16-pin package drawing and PCB footprint before using those listings for a design.

How these product options work

• Dedicated SN74HC595N lots: fixed 10-, 20-, 50-, 100- and 200-piece headlines appear in this collection. In another listing, the title says 20pcs but the Model Number selector offers 5pcs, 10pcs or 20pcs; choose the intended option rather than assuming every order contains 20. A Default Title item has no alternate model selector, so read its individual quantity statement.
• Multi-model chip menus: Color often means model and lot size, for example SN74HC595N 5PCS, 20PCS or 100PCS alongside unrelated INS8040N-11, LM2574M-ADJ, BP2833D, STM32F051C8T6 or 2SC9015 options. Choosing a non-595 option does not supply an SN74HC595N.
• Logic-family menus: separate choices include SN74HC00N, SN74HC04N, SN74HC08N, SN74HC14N, SN74HC32N, SN74HC74N, SN74HC86N, SN74HC138N, SN74HC165N, SN74HC257N, SN74HC393N and SN74HC590AN. These chips perform different gate, flip-flop, counter, decoder or input-register functions. A 10PCS headline with a single selected model usually describes ten of that option, not ten of every chip named in the title.
• Mixed assortment kits: a 12-value/60-piece DIP kit names SN74HC595N among other logic ICs and mentions IC sockets; an 80-piece logic kit also names it among multiple types. These are assortments rather than a 60- or 80-piece lot of SN74HC595N. Check the product-specific packing list for the quantity of each model and whether sockets are actually included. The 80-piece kit headline's blanket 'DIP-14' wording must not be applied to SN74HC595N.
• Non-595 cross-listed item: a product title starts 'SN74HC595N SI4943BDY', but its only Model Number value is SI4943BDY-T1-E3 and Color changes only 2/3/5/10PCS. Those shown choices do not establish an SN74HC595N option. Check that listing's exact orderable variant instead of assuming the headline guarantees a 595.

Distinguish lookalikes and unrelated parts

SN74HC165N is a parallel-input shift register used for a different direction of data transfer; SN74HC164N is another serial-input register but is not a drop-in 595 with an identical output latch. SN74HC257N is a multiplexer, SN74HC393N a counter and SN74HC590AN a counter/register device. SN74HCT165M or SN74HCT138N is also a different function and logic family; HC, HCT, LS and other logic prefixes should not be collapsed into a universal compatibility promise. A listing may combine the 595 with MAX232EPE, TL494CN, LM324N, NE555, ULN2803APG, L293D, PT2399, memory, microcontrollers, relays, power-management parts, transistors or triacs. Those selected alternatives are not SN74HC595N and may have different packages and electrical requirements. Review both the model text and the piece count printed on the selected variant, particularly where option strings are truncated.

Engineering checks for a correct purchase

1. Package and order code: match the full part number, 16-pin PDIP footprint, pin-one indication and manufacturer package drawing. A 595 in SOP-16 is not a socketable N-suffix through-hole part merely because the circuit function is similar.
2. Logic levels: use the selected manufacturer's recommended VCC, VIH and VIL specifications. A controller and chip powered at different rails are not automatically level-compatible. Check HC versus HCT separately.
3. Timing: validate serial-data setup/hold, shift clock, storage clock, reset and output-enable behavior at your clock speed and operating voltage; account for propagation delays across a cascaded chain.
4. Load and thermal budget: read per-output and total package current limits and output-voltage conditions in the chosen datasheet. Use suitable LED current limiting or an external load driver when required. An SN74HC595N chip by itself is not an assembled LED display, a power relay driver or a guaranteed high-current output stage.
5. Order contents: check whether the item is one model in a multi-model menu, a fixed-count chip lot, or a genuinely mixed kit. 'New original', 'import original' and branded wording in seller titles are not independent authentication or test reports.

Frequently asked questions

What is SN74HC595N used for?

It converts serial logic data to an eight-bit latched parallel output pattern, commonly useful when a controller needs additional digital outputs within the selected device's electrical limits. It requires an appropriate external circuit and control signals.

Does a listing with twelve chip names include all twelve?

Not necessarily. Most Color menus here pick a single chip type and sometimes a quantity. Only listings identified as assortments indicate multiple included models, and their exact packing breakdown should be confirmed on the individual product.

Is DIP-14 a safe footprint for SN74HC595N?

No. Some headlines conflict with the usual 16-pin SN74HC595N package. Verify the complete part and its package drawing before ordering a socket or PCB.

Are 74HC595D and SN74HC595N physically interchangeable?

No. The D/SOP-16 and N/DIP-16 choices identify different mounting formats. Verify manufacturer-specific electrical characteristics as well as physical dimensions before substitution.

Can I use an SN74HC165N instead of SN74HC595N?

No direct substitution follows from the similar name. The 165 captures parallel inputs for serial readout; the 595 creates latched parallel outputs from serial data. Match the required function and pinout.
