SN54HC595, SN74HC595 is 8-bit serial-in, parallel-out shift registers with 3-state output registers.
The document describes the SN54HC595 and SN74HC595 devices, which contain an 8-bit serial-in, parallel-out shift register that feeds an 8-bit D-type storage register. The storage register features parallel 3-state outputs, allowing up to 15 LSTTL loads to be driven by the high-current output pins.
The datasheet details absolute maximum ratings, recommended operating conditions, and electrical characteristics for both military (SN54HC595) and commercial (SN74HC595) grade devices. It includes timing requirements, switching characteristics under various load conditions, and logic diagrams with pin definitions.
