The 74HC/HCT595 are high-speed Si-gateCMOSdevices and are pin compatible with low power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard no. 7A. The 74HC/HCT595 is an 8-stage serial shift register with a storage register and 3-state outputs. The shift register and storage register have separate clocks.
The 74HC/HCT595 are high-speed Si-gate CMOS devices that are pin compatible with low power Schottky TTL (LSTTL). They function as an 8-stage serial shift register with a separate storage register, allowing for data shifting on the positive-going transitions of the SH_CP input and transfer to parallel outputs on the ST_CP input.
The device features asynchronous reset capabilities and is available in various packages including DIP16, SO16, SSOP16, TSSOP16, and DHVQFN16. It supports applications such as serial-to-parallel data conversion and remote control holding registers.

It is an 8-stage serial shift register with a storage register and 3-state outputs.
Data in each register is transferred to the storage register on a positive-going transition of the ST_CP input.
