MC74HCT595ADG Datasheet, PDF (1/11 Pages) ON Semiconductor – 8-Bit Serial-Input/Serial or Parallel-Output Shift Register with Latched 3-State Outputs and LSTTL Compatible Inputs

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.
