Semiconductor

SLS

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 compatible with standard CMOS outputs; with pullup

resistors, they are compatible with LS/ALSTTL outputs.

The SL74HC595 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 re set

for the shift register.

• 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
