CD74HC125QM96Q1

Overview

The CD74HC125QM96Q1 is an automotive-grade, high-speed CMOS quad buffer and line driver manufactured by Texas Instruments. It features four non-inverting buffers with three-state outputs controlled by active-low enable inputs. The device 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. It is designed for robust performance in demanding environments, meeting AEC-Q100 qualification standards for automotive applications.

Feature Summary

• Automotive grade reliability compliant with AEC-Q100 standards
• High-speed CMOS technology for efficient signal buffering
• Three-state outputs allow direct connection to bus lines
• Wide operating voltage and temperature ranges

Applications

• Automotive electronic control units (ECUs)
• Bus-oriented transmissions
• Clock drivers
• Buffering memory data buses

Procurement Notes

Verify the specific suffix 'QM96Q1' against official Texas Instruments documentation to confirm package type and automotive qualification status. Ensure compatibility with required operating temperatures and voltage levels for the target application before procurement.

Selection Notes

Select this component when designing systems requiring buffered signals with three-state capability in automotive or industrial environments. Consider the 2V to 6V supply range and ensure the load capacitance requirements are met for the desired propagation delay performance.

Part Context

This part belongs to the SN74HC125 family of quad buffers with three-state outputs. The 'Q1' suffix indicates automotive qualification, while 'M96' typically denotes a specific tape-and-reel packaging configuration suitable for automated surface-mount assembly processes.

Replacement Considerations

Check for SN74HCS125 variants for Schmitt-trigger input options or SN74HC125 variants for standard commercial grade if automotive qualification is not strictly required. Verify pinout compatibility before substitution.
