SL74HC597

System Logic

Semiconductor

SLS

8-Bit Serial or Parallel-Input/ Serial-Output Shift

Register with Input Latch

High-Performance Silicon-Gate CMOS

The SL74HC597 is identical in pinout to the LS/ALS597. The device

inputs are compatible with standard CMOS outputs; with pullup

resistors, they are compatible with LS/ALSTTL outputs.

This device consists of an 8-bit input latch which feeds parallel

data to an 8-bit shift register. Data can also be loaded serially (see

Function Table).

• Outputs Directly Interface to CMOS, NMOS, and TTL

• Operating Voltage Range: 2.0 to 6.0 V

• Low Input Current: 1.0 µA

• High Noise Immunity Characteristic of CMOS Devices
