Description

The MM74HC595 high-speed shift register utilizes

advanced silicon-gate CMOS technology. This device

possesses the high noise immunity and low power

consumption of standard CMOS integrated circuits, as

well as the ability to drive 15 LS-TTL loads.

This device contains an eight-bit serial-in, parallel-out,

shift register that feeds an eight-bit D-type storage

register. The storage register has eight 3-state outputs.

Separate clocks are provided for both the shift register

and the storage register. The shift register has a direct-

overriding clear, serial input, and serial output

(standard) pins for cascading. Both the shift register

and storage register use positive-edge triggered clocks.

If both clocks are connected together, the shift register

state is one clock pulse ahead of the storage register.

The 74HC logic family is speed, function, and pin-out

compatible with the standard 74LS logic family. All

inputs are protected from damage due to static

discharge by internal diode clamps to VCC and ground.
