8-Bit Shift Register

Overview

High-Performance Silicon-Gate CMOS

The MC74HC589A is similar in function to the HC597, which is not a 3-state device. The device inputs are compatible with standard CMOS outputs, with pullup resistors, they are compatible with LSTTL outputs.

This 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 Function Table). The shift register output, QH, is a three-state output, allowing this device to be used in bus-oriented systems.

The HC589A 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 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
