MOTOROLA
SEMICONDUCTOR TECHNICAL DATA
8-Bit Serial-Input/Serial or
Parallel-Output Shift Register
with Latched 3-State Outputs
High–Performance Silicon–Gate CMOS
The MC54/74HC595A is identical in pinout to the LS595. The device
inputs are compatible with standard CMOS outputs; with pullup resistors,
they are compatible with LSTTL outputs.
The HC595A 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 HC595A directly interfaces with the Motorola SPI serial data port on
CMOS MPUs and MCUs.
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 A
High Noise Immunity Characteristic of CMOS Devices
In Compliance with the Requirements Defined by JEDEC Standard
No. 7A
Chip Complexity: 328 FETs or 82 Equivalent Gates
Improvements over HC595
— Improved Propagation Delays
— 50% Lower Quiescent Power
— Improved Input Noise and Latchup Immunity
