74AHC3G14DP-Q100H

Overview

The Nexperia 74AHC3G14DP-Q100H is a triple inverting Schmitt trigger logic device designed for automotive applications. It operates within a supply voltage range of 2.0 V to 5.5 V and features overvoltage tolerant inputs up to 5.5 V, enabling use as translators in mixed-voltage environments. The component is qualified to AEC-Q100 Grade 1 standards and supports ambient temperatures from -40 °C to +125 °C. It utilizes the TSSOP8 (SOT505-2) plastic thin shrink small outline package with eight leads.

Feature Summary

• Triple inverting Schmitt trigger configuration with high noise immunity
• Automotive qualification compliant with AEC-Q100 Grade 1 standard
• Overvoltage tolerant inputs allowing operation in mixed-voltage systems
• Symmetrical output impedance with balanced propagation delays

Applications

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

Procurement Notes

Verify that the specific part number suffix matches the required temperature grade and package variant. Confirm compliance with relevant environmental directives such as RoHS and REACH during procurement. Ensure design specifications align with the absolute maximum ratings provided in the datasheet to prevent permanent damage. Cross-reference marking codes to validate authenticity upon receipt.

Selection Notes

Select this component when a triple inverter with Schmitt-trigger action is required for signal conditioning in automotive or industrial settings. The wide supply voltage range facilitates integration into various power domains. Consider the TSSOP8 package dimensions if board space is constrained. Verify input logic levels match the CMOS requirements specified for the AHC series rather than TTL levels.

Part Context

This device belongs to the Nexperia 74AHC_AHCT3G14_Q100 family of triple inverters. It shares functional similarities with other members of the series but differs in input threshold characteristics and specific package options. The DP suffix indicates the TSSOP8 package, while the Q100H suffix denotes automotive qualification and halogen-free manufacturing status.

Replacement Considerations

Direct substitutes include the 74AHCT3G14DP-Q100H for TTL-compatible input thresholds. Other variants within the same family may offer different package types such as VSSOP8.
