CD74HC125QPWRQ1

Overview

The CD74HC125QPWRQ1 is an automotive-grade, high-speed CMOS logic device featuring four non-inverting buffers with three-state outputs. Manufactured by Texas Instruments, it operates within a supply voltage range of 2 V to 6 V and supports a wide operating temperature range from -40°C to +125°C. The component utilizes a 14-pin TSSOP package and meets AEC-Q100 qualification standards for automotive applications.

Feature Summary

• Automotive qualification compliant with AEC-Q100 standards
• High-speed CMOS technology for efficient signal buffering
• Three-state output capability for bus-oriented systems

Applications

• Automotive electronic control units
• Bus-oriented memory and data transmission systems
• Industrial control systems requiring wide temperature operation

Procurement Notes

Verify the specific suffix 'Q1' confirms automotive grade status and AEC-Q100 compliance. Ensure the 'PWR' suffix corresponds to the TSSOP-14 package variant required for your PCB layout. Confirm RoHS compliance details in the official datasheet before finalizing procurement specifications.

Selection Notes

Select this component when designing for automotive environments requiring robust performance across extreme temperatures. It serves as a direct functional replacement for standard HC125 devices where automotive reliability and extended temperature ranges are mandatory. Verify pin compatibility with existing designs if substituting non-automotive variants.

Part Context

This part belongs to the SN74HC125 family of quad bus buffers. The 'Q1' designation indicates it is part of Texas Instruments' Automotive Catalog line, ensuring higher reliability and stricter manufacturing controls compared to commercial grade equivalents. It shares logical functionality with the SN74HC125 but differs in qualification and environmental ratings.
