SL74HC597
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
