74HC125PW-Q100J

Overview

The Nexperia 74HC125PW-Q100J is a quad buffer and line driver featuring three-state outputs, qualified to AEC-Q100 Grade 1 standards for automotive reliability. It operates within a supply voltage range of 2.0 V to 6.0 V and supports ambient temperatures from -40 °C to +125 °C. The device utilizes CMOS technology with Schmitt-trigger inputs for high noise immunity and includes input clamp diodes for interfacing with voltages exceeding VCC. It is housed in a TSSOP14 (SOT402-1) package.

Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 specifications
• Quad non-inverting buffers with active LOW output enable control
• High noise immunity via Schmitt-trigger action on all inputs
• ESD protection exceeding 2000 V HBM and 1000 V CDM

Applications

• Automotive engine control units
• Body control modules
• Transmission control units
• Electronic instrument clusters

Procurement Notes

Verify current production status directly with the manufacturer or authorized distributors, as availability may fluctuate. Confirm that the specific PW suffix corresponds to the TSSOP14 package variant required for your PCB layout. Ensure compliance with RoHS directives and check for any recent product change notices affecting marking or assembly processes before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring robust signal buffering in automotive environments. The wide supply voltage range accommodates various system power rails. Verify that the logic levels match the driving source, as this HC variant uses CMOS thresholds. Consider the thermal derating characteristics if operating near the upper temperature limits in enclosed spaces.

Part Context

This part belongs to the 74HCS125/74HC125 family of quadruple bus buffers. The 'Q100' designation indicates automotive-grade qualification, while the 'PW' suffix specifies the thin shrink small outline plastic package. It serves as a standard interface solution for managing multiple data lines in complex electronic systems where signal integrity and isolation are critical.

Replacement Considerations

The 74HCT125PW-Q100J is a pin-compatible alternative offering TTL input levels instead of CMOS levels. Designers must verify voltage compatibility between the driving circuit and the new input threshold requirements before substituting.
