74AHCT1G79GW-Q100H

Overview

The 74AHCT1G79GW-Q100H is a single D-type flip-flop with positive-edge triggering, designed for automotive applications. It operates within a supply voltage range of 4.5V to 5.5V and features non-inverting outputs capable of sourcing and sinking 8mA. The device exhibits a maximum propagation delay of 8ns at 5V with 50pF load and a clock frequency of 90MHz. Static current consumption is 1µA. It is housed in a 5-TSSOP package (SC-70-5/SOT-353) and supports an operating temperature range from -40°C to 125°C.

Feature Summary

• Automotive-grade qualification compliant with AEC-Q100 standards
• Positive-edge triggered D-type flip-flop functionality
• High noise immunity with CMOS low power dissipation characteristics

Applications

• Automotive data storage and register circuits
• Synchronization logic in vehicle control modules
• State machine implementation in automotive ECUs

Procurement Notes

Verify the specific suffix Q100H confirms AEC-Q100 Grade 1 automotive qualification and extended temperature range support up to 125°C. Ensure the GW package designation matches the required 5-TSSOP footprint. Confirm RoHS3 compliance status if environmental regulations apply. Cross-reference the manufacturer part number against official Nexperia distribution channels to avoid counterfeit components.

Selection Notes

Select this component when a single-bit storage element is required in 5V automotive systems. The AHCT series ensures TTL-compatible input levels while maintaining CMOS performance. Consider the 8ns propagation delay and 90MHz clock limit for timing constraints. The wide operating temperature range makes it suitable for harsh automotive environments compared to standard commercial variants.

Part Context

This part belongs to the Nexperia 74AHCT1G79-Q100 family of single D-type flip-flops. It is specifically engineered for automotive electronics, meeting rigorous reliability standards. The device provides a compact solution for sequential logic in space-constrained automotive PCBs, offering a balance of speed, power efficiency, and robustness.

Replacement Considerations

The 74AHCT1G79GW,125 is a parameter-equivalent alternative available from Nexperia. Verify that the non-Q100 variant meets the specific automotive qualification requirements of the target application before substitution.
