74AHC1G79GW-Q100H

Overview

The Nexperia 74AHC1G79GW-Q100H is a single D-type flip-flop in a 5-TSSOP package, designed for automotive applications with AEC-Q100 qualification. It operates on a supply voltage of 2V to 5.5V, featuring non-inverting outputs and positive-edge triggering. The device supports a clock frequency up to 90 MHz, with a maximum propagation delay of 8ns at 5V and 50pF load. It delivers 8mA output current, draws 1µA static current, and functions within a temperature range of -40°C to 125°C.

Feature Summary

• Automotive-grade reliability certified under AEC-Q100 standards
• Positive-edge triggered D-type flip-flop configuration
• Wide operating supply voltage range from 2V to 5.5V

Applications

• Automotive electronic control units
• Data storage and register circuits
• Shift registers in high-speed logic systems

Procurement Notes

Verify the complete part number including the Q100 suffix to ensure automotive grade compliance. Confirm the GW variant matches the required 5-TSSOP surface mount package. Check RoHS3 status and MSL rating for assembly compatibility. Validate that the specific ordering code aligns with your bill of materials requirements.

Selection Notes

Select this component when automotive certification is mandatory for single-bit storage applications. Choose over standard variants if extended temperature operation and qualified reliability are required. Ensure the 5.5V maximum supply voltage fits the system design constraints.

Part Context

This part belongs to the 74AHC(T)1Gxx-Q100 family of single-gate automotive logic devices. It shares the 5-TSSOP footprint with other members like the 74AHCT1G79GW-Q100H but differs in speed and voltage threshold characteristics. The series provides compact solutions for space-constrained automotive designs.

Replacement Considerations

The 74AHCT1G79GW-Q100H is a parameter-equivalent alternative within the same manufacturer's lineup. Verify voltage threshold compatibility between AHCT and AHC families before substitution.
