MC74HCT595A

8-Bit Serial-Input/Serial or

Parallel-Output Shift

Register with Latched

3-State Outputs and LSTTL

Compatible Inputs

High−Performance Silicon−Gate CMOS

The MC74HCT595A 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.

The HCT595A directly interfaces with the SPI serial data port on

CMOS MPUs and MCUs. The device inputs are compatible with

standard CMOS or LSTTL outputs.

Features
