TECHNICAL DATA
8-Bit Serial or Parallel-Input/
Serial-Output Shift Register
with Input Latch
High-Performance Silicon-Gate CMOS
IN74HC597A
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
