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 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 reset
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
