74AHC1G79GV-Q100H

Overview

The 74AHC1G79GV-Q100H is a single positive-edge triggered D-type flip-flop manufactured by Nexperia USA Inc. It operates within a wide supply voltage range of 2.0 V to 5.5 V and features overvoltage tolerant inputs capable of withstanding up to 5.5 V, facilitating use in mixed-voltage environments. The device provides high noise immunity and low power dissipation typical of CMOS technology. It includes ESD protection exceeding 2000 V (HBM) and 1000 V (CDM). The component is qualified to AEC-Q100 standards for automotive applications and is specified for operation across an extended temperature range from -40 °C to +125 °C.

Feature Summary

• Single positive-edge triggered D-type flip-flop functionality
• Overvoltage tolerant inputs for mixed-voltage translation
• High noise immunity and low power consumption
• Extended industrial temperature range specification

Applications

• Automotive data storage circuits
• Mixed-voltage signal translation interfaces
• General-purpose digital logic registers

Procurement Notes

Verify the specific suffix GV against official Nexperia documentation to confirm package type and tape/reel specifications. Ensure the Q100 designation aligns with required automotive qualification standards for the target application. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm current availability and lead times prior to procurement.

Selection Notes

Select this component when a single D-type flip-flop with overvoltage tolerant inputs is required in a small surface-mount package. The AHC series offers higher speed than standard HC devices while maintaining CMOS compatibility. Consider the 74AHCT variant if TTL input levels are necessary instead of CMOS levels.

Part Context

This part belongs to the Nexperia 74AHC(T)1Gxx-Q100 family of single-function logic devices designed for automotive and industrial applications. The family utilizes advanced CMOS technology to provide high-speed operation with low power consumption. These components are pin-compatible with other single-gate logic families, simplifying PCB layout and design reuse across different functional requirements.

Replacement Considerations

The 74AHC1G79GW-Q100H is a documented equivalent substitute with identical electrical characteristics but a different package option (TSSOP vs SC-74A/SC-88). Verify mechanical footprint compatibility before substitution.
