3 Description

The SN74HCS595-Q1 device contains an 8-bit, serial-

in, parallel-out shift register that feeds an 8-bit D-type

storage register. All inputs include Schmitt-trigger

architecture, eliminating any erroneous data outputs

due to slow-edged or noisy input signals. The storage

register has parallel 3-state outputs. Separate clocks

are provided for both the shift and storage register.

The shift register has a direct overriding clear

(SRCLR) input, serial (SER) input, and a serial output

input is high, the storage register outputs are in a

high-impedance state. Internal register data and serial

OE input.
