SL74HC595 Overview
SL74HC595 8-Bit Serial-Input/Serial or Parallel-Output Shift Register with Latched 3-State Outputs High-Performance Silicon-Gate CMOS The SL74HC595 is identical in pinout to the LS/ALS595. The device inputs are patible with standard CMOS outputs; with pullup resistors, they are patible with LS/ALSTTL outputs.
