74AHCT3G14DP-Q100H

Overview

The Nexperia 74AHCT3G14DP-Q100H is a triple inverting Schmitt trigger integrated circuit designed for automotive applications. It operates within a supply voltage range of 2.0 V to 5.5 V and features TTL-compatible input levels. The device provides overvoltage tolerant inputs up to 5.5 V, ensuring compatibility in mixed-voltage environments. It is qualified to AEC-Q100 Grade 1 standards and supports an ambient temperature range from -40 °C to +125 °C.

Feature Summary

• Triple inverting Schmitt trigger configuration with high noise immunity
• Automotive qualification compliant with AEC-Q100 Grade 1 standards
• Overvoltage tolerant inputs allowing operation in mixed-voltage systems
• TTL-level input logic compatibility

Applications

• Wave and pulse shaping in highly noisy environments
• Astable multivibrator circuits
• Monostable multivibrator circuits

Procurement Notes

Verify the specific suffix 'Q100H' against official Nexperia documentation to confirm package type and tape-and-reel specifications. Ensure the design meets AEC-Q100 Grade 1 requirements for the target automotive environment. Confirm that the TSSOP8 (SOT505-2) footprint matches the PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this component when TTL-level input thresholds are required alongside Schmitt-trigger action for signal conditioning. The wide supply voltage range accommodates various system power rails. Verify that the operating temperature range extends to +125 °C if the application involves high thermal stress or under-the-hood automotive conditions.

Part Context

This part belongs to the Nexperia 74AHC_AHCT3G14-Q100 family of triple inverters. The 'AHCT' designation indicates CMOS technology with TTL-compatible inputs, distinguishing it from standard AHC variants. The 'DP' suffix identifies the TSSOP8 plastic thin shrink small outline package, while the 'Q100' suffix denotes automotive qualification.

Replacement Considerations

The 74AHC3G14DP-Q100H serves as a functional alternative where CMOS input levels are acceptable instead of TTL levels. Both devices share identical pinouts, packages, and automotive qualifications.
