74HC595
8−Bit Serial−Input/Serial or
Parallel−Output Shift
Register with Latched
3−State Outputs
High−Performance Silicon−Gate CMOS
The 74HC595 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 HC595 directly interfaces with the SPI serial data port on
CMOS MPUs and MCUs.
