SEMICONDUCTOR TECHNICAL DATA
8-Bit Serial or Parallel-Input/ Serial-Output Shift Register with Input Latch
High–Performance Silicon–Gate
CMOS
The MC54/74HC597 is identical in pinout to the LS597.
The device inputs are compatible with standard
CMOS outputs; with pullup resistors, they are compatible with LSTTL 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).
The HC597 is similar in function to the HC589, which is a 3–state device.
