74AHCT1G32GV-Q100,

Overview

The Nexperia 74AHCT1G32GV-Q100 is a single 2-input OR gate in the 74AHCT logic family, housed in an SC-74A (SOT753) package. It operates within a supply voltage range of 4.5 V to 5.5 V and supports input voltages up to 5.5 V. The device features TTL-compatible input levels, symmetrical output impedance, and balanced propagation delays. It is qualified to AEC-Q100 Grade 1 standards for automotive applications and functions reliably across an ambient temperature range of -40 °C to +125 °C.

Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 specifications
• TTL-level input compatibility enabling direct interfacing with legacy logic systems
• Overvoltage tolerant inputs allowing operation in mixed-voltage environments

Applications

• Automotive electronic control units requiring robust logic gating
• Mixed-signal circuit translation between TTL and CMOS domains
• Industrial control systems operating under high noise immunity requirements

Procurement Notes

Verify that the ordering suffix matches the specific SC-74A package configuration required for your PCB layout. Confirm the AEC-Q100 Grade 1 qualification status aligns with your automotive reliability standards. Ensure the supply voltage provided strictly adheres to the 4.5 V to 5.5 V recommended operating conditions to maintain specified performance metrics.

Selection Notes

Select this component when TTL input thresholds are necessary within a CMOS-based design architecture. The AHCT series provides the speed advantages of advanced CMOS technology while maintaining compatibility with standard TTL logic families. Consider the wide operating temperature range if the application environment exceeds standard commercial limits.

Part Context

This part belongs to the 74AHC/AHCT1G32-Q100 family of single 2-input OR gates manufactured by Nexperia. The family includes variants such as the 74AHC1G32GW-Q100 and 74AHCT1G32GW-Q100, which share identical logical functionality but differ in package types like TSSOP5 or XSON5. All variants maintain the same automotive-grade qualification and core electrical characteristics defined in the product data sheet.

Replacement Considerations

Direct substitutes include other 74AHCT1G32 parts from different manufacturers that meet AEC-Q100 Grade 1 standards. Verify pinout compatibility with the SC-74A package before replacement. Ensure the alternative component supports the required 5.5 V overvoltage tolerance on inputs.
