74HC1G125GW-Q100H

Overview

The Nexperia 74HC1G125GW-Q100H is a single non-inverting buffer and line driver featuring a three-state output, qualified to AEC-Q100 Grade 1 for automotive use. It operates on a supply voltage range of 2.0 V to 6.0 V with CMOS input levels. The device utilizes a TSSOP5 (SOT353-1) package with five leads and a body width of 1.25 mm. It supports an ambient temperature range from -40 °C to +125 °C and includes input clamp diodes for interfacing with voltages exceeding VCC.

Feature Summary

• Automotive qualification in accordance with AEC-Q100 Grade 1 standards
• Wide supply voltage operation ranging from 2.0 V to 6.0 V
• High noise immunity with symmetrical output impedance and balanced propagation delays
• ESD protection exceeding 2000 V via Human Body Model and 1000 V via Charged Device Model

Applications

• Automotive electronic systems requiring high reliability
• Bus buffering and line driving applications
• Interfaces utilizing current limiting resistors for voltage translation

Procurement Notes

Verify the specific ordering suffix 'H' against official Nexperia documentation to confirm packaging details such as tape and reel specifications. Ensure the component matches the SOT353-1 package variant. Confirm that the procurement channel provides valid traceability records required for automotive-grade components. Cross-reference the marking code HM with the datasheet to validate authenticity.

Selection Notes

Select this component when a single-channel buffer with three-state control is required for automotive environments. The HC series offers CMOS input switching levels suitable for standard logic interfaces. Consider the wide supply voltage range if the system design involves varying power rails between 2.0 V and 6.0 V. Verify that the thermal dissipation requirements align with the specified derating curves for the TSSOP5 package.

Part Context

This part belongs to the 74HC1G125-Q100 family of bus buffers and line drivers manufactured by Nexperia. It is designed specifically for automotive applications, meeting rigorous quality standards defined by the Automotive Electronics Council. The device serves as a fundamental building block for signal conditioning and isolation in complex vehicle electronics architectures.

Replacement Considerations

The 74HC1G125GV-Q100H is a verified substitute offering identical electrical characteristics but housed in a SC-74A (SOT753) package.
