MC74HC589ANG

Shift Registers Overview

The MC74HC589ANG is an 8-bit serial or parallel-input/serial-output shift register manufactured by onsemi. It features a storage latch that feeds parallel data to the shift register, with serial loading capability. The device provides a 3-state output at QH, enabling use in bus-oriented systems. It operates within a supply voltage range of 2V to 6V and interfaces directly with SPI serial data ports on CMOS microprocessors and microcontrollers.

Shift Registers Feature Summary

• Provides 8-bit serial or parallel input and serial output functionality
• Features 3-state outputs for bus-oriented system integration
• Directly interfaces with SPI serial data ports on CMOS MPUs and MCUs

Shift Registers Applications

• Bus-oriented digital systems requiring data shifting
• SPI serial data port interfacing for CMOS microprocessors
• Microcontroller peripheral expansion

Shift Registers Procurement Notes

Verify the specific suffix 'ANG' against official onsemi documentation to confirm package type and temperature grade. Confirm current availability status as older HC series variants may be discontinued or replaced by updated revisions. Ensure compatibility with existing PCB footprints and design specifications before procurement.

Shift Registers Selection Notes

Select this component when an 8-bit shift register with 3-state outputs is required for SPI interface applications. Verify that the 2V to 6V operating voltage range matches the system power supply. Consider the PDIP-16 package constraints for through-hole mounting requirements and ensure signal integrity meets noise immunity standards for the target environment.

Shift Registers Part Context

This part belongs to the 74HC logic family, utilizing high-performance silicon-gate CMOS technology. It is designed for low input current and high noise immunity. The device contains approximately 526 FETs and complies with JEDEC Standard No. 7A.
