TECHNICAL DATA
IN74HC595A
8-Bit Serial-Input/Serial or
Parallel-Output Shift Register
with Latched 3-State Outputs
High-Performance Silicon-Gate CMOS
The IN74HC595A is identical in pinout to the LS/ALS595. The device
inputs are compatible with standard CMOS outputs; with pullup resistors,
they are compatible with LS/ALSTTL outputs.
The IN74HC595A consists of an 8-bit shift register and an 8-bit D-
type latch with three-state parallel outputs. The shift register accepts serial
data and provides a serial output. The shift register also provides parallel
data to the 8-bit latch. The shift register and latch have independent clock
inputs. This device also has an asynchronous reset for the shift register.
