MC74HC589A

8-Bit Serial or Parallel-Input/Serial-Output Shift Register with 3-State Output

ON Semiconductor 

MC74HC589A

8−Bit Serial or

Parallel−Input/Serial−Output

Shift Register with 3−State

Output

High−Performance Silicon−Gate CMOS

The MC74HC589A device consists of an 8−bit storage latch which

feeds parallel data to an 8−bit shift register. Data can also be loaded

serially (see the Function Table). The shift register output, QH, is a

3−state output, allowing this device to be used in bus−oriented

systems.

The HC589A 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 to 6 V

• Low Input Current: 1 mA

• High Noise Immunity Characteristic of CMOS Devices

• In Compliance with the Requirements Defined by JEDEC

Standard No. 7A

• Chip Complexity: 526 FETs or 131.5 Equivalent Gates

• Pb−Free Packages are Available*
