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.
Features
• Output Drive Capability: 15 LSTTL Loads
• Outputs Directly Interface to CMOS, NMOS, and TTL
• Operating Voltage Range: 2.0 to 6.0 V
• Low Input Current: 1.0 mA
• High Noise Immunity Characteristic of CMOS Devices
• In Compliance with the Requirements Defined by JEDEC
Standard No. 7A
• ESD Performance: HBM > 2000 V; Machine Model > 200 V
• Chip Complexity: 328 FETs or 82 Equivalent Gates
• Improvements over HC595
− Improved Propagation Delays
− 50% Lower Quiescent Power
− Improved Input Noise and Latchup Immunity
• These are Pb−Free Devices
