8-Bit Serial or Parallel-Input/Serial-Output Shift Register with Input Latch

High-Performance Silicon-Gate CMOS

The IN74HC597A 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
