MC74HC595A - 8-Bit Serial-Input/Serial or Parallel-Output Shift Register
MOTOROLA SEMICONDUCTOR TECHNICAL DATA 8-Bit Serial-Input/Serial or Parallel-Output Shift Register with Latched 3-State Outputs High Performance Silicon Gate CMOS The MC54/74HC595A is identical in pinout to the LS595.
The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs.
The HC595A consists of an 8 bit shift register and an 8 bit D type latch with three state parallel outputs.
