Replacement verdict
Compatible functional replacement candidate
The 74HC595D and 74HC595D,112 are functionally equivalent 8-bit serial-in/parallel-out shift registers with output latches from the same manufacturer family. Both share identical logic function, package type, and electrical characteristics, making the 74HC595D,112 a viable functional replacement candidate for the 74HC595D in most designs. The primary distinction lies in the ordering and packaging format, which does not affect electrical performance or footprint compatibility.

Frequently asked questions
Are the 74HC595D and 74HC595D,112 the same device?
Yes. Both part numbers refer to the same 8-bit serial-in, parallel-out shift register with output latches from Nexperia. The 74HC595D is the base type designation, while 74HC595D,112 is the full orderable part number that includes the packing method. The ,112 suffix indicates tape and reel packaging in a 16-pin SO package.
What is the difference between the 74HC595D and 74HC595D,112?
The electrical and functional characteristics are identical. The only difference is the ordering and packaging designation. The 74HC595D,112 specifies tape and reel packing, while the 74HC595D may be ordered under different packing suffixes depending on the supplier. Both use the same 16-pin SO (SOT109-1) package.
Can the 74HC595D and 74HC595D,112 be used interchangeably in a design?
Yes. Since both part numbers refer to the same die, package, and electrical specifications, they are functionally interchangeable. Any design that works with one will work with the other, provided the physical package and packing method meet the assembly requirements.
What package do the 74HC595D and 74HC595D,112 use?
Both devices are supplied in a 16-pin SO package, also designated SOT109-1. This is a small-outline surface-mount package with a 1.27 mm pitch, suitable for standard SOIC-16 PCB footprints.
What are the key operating parameters of the 74HC595D and 74HC595D,112?
Both devices operate over a supply voltage range of 2.0 V to 6.0 V, with typical operation at 5 V. They feature an 8-bit serial-in, parallel-out shift register with a storage register and 3-state output registers. Maximum shift and storage frequency is typically 100 MHz at 5 V. Output drive capability is ±6 mA per output at 5 V.
Do the 74HC595D and 74HC595D,112 have the same pinout?
Yes. Both use the standard 74HC595 pinout in the 16-pin SO package. Pin functions include serial data input (DS), shift clock (SHCP), storage clock (STCP), output enable (OE), reset (MR), and eight parallel outputs (Q0–Q7) plus serial output (Q7S).
Which manufacturers produce the 74HC595D and 74HC595D,112?
The 74HC595D and 74HC595D,112 are manufactured by Nexperia (formerly NXP Semiconductors). The ,112 suffix is a Nexperia-specific packing code. Equivalent devices are also available from other manufacturers such as Texas Instruments (SN74HC595) and ON Semiconductor (MC74HC595A), but these are separate part numbers with their own specifications.
What does the ,112 suffix mean on the 74HC595D,112?
The ,112 suffix is Nexperia's packing and ordering code. It indicates that the device is supplied in tape and reel format for automated assembly. The base part 74HC595D without this suffix may be available in different packing options such as tubes or trays, depending on the supplier's ordering information.
