74AHCT1G79GV-Q100H

Overview

The Nexperia 74AHCT1G79GV-Q100H is a single D-type flip-flop with positive-edge triggering, designed for automotive applications under AEC-Q100 Grade 1 qualification. 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 3.5ns at 5V with 50pF load and supports clock frequencies up to 90MHz. Packaged in SC-74A-5 (SOT753), it ensures reliable performance across an extended temperature range of -40°C to +125°C.

Feature Summary

• Positive-edge triggered D-type flip-flop functionality with non-inverting output
• Automotive-grade reliability certified to AEC-Q100 standards
• High-speed data storage with low propagation delay characteristics
• Robust noise immunity suitable for demanding automotive environments

Applications

• Automotive data storage systems requiring high reliability
• Shift registers in automotive control modules
• Bus latch applications for signal holding
• General-purpose memory elements in vehicle electronics

Procurement Notes

Verify the specific suffix 'GV' against official Nexperia documentation to confirm the SC-74A-5 package designation. Ensure the Q100H variant matches the required automotive grade specifications. Cross-reference the manufacturer part number with authorized distributors to confirm current availability and lead times. Validate that the component meets all relevant RoHS and environmental compliance requirements for your specific application needs.

Selection Notes

Select this component when a single-bit storage element with positive-edge triggering is required in automotive designs. It is appropriate for interfaces needing TTL-compatible input levels due to the HCT series logic family. Consider this part for space-constrained PCB layouts utilizing the small SC-74A-5 package. Ensure the operating voltage aligns with the 4.5V to 5.5V specification range for proper functionality.

Part Context

This component belongs to the 74AHCT1G79-Q100 family of single D-type flip-flops. It shares functional similarities with other automotive-qualified logic devices from Nexperia but offers specific timing and packaging advantages. The GV suffix typically denotes the SC-74A-5 package, distinguishing it from other variants like GW or GZ. It serves as a fundamental building block for sequential logic circuits in modern automotive electronic systems.

Replacement Considerations

The 74AHCT1G79GW-Q100H is a confirmed substitute with identical electrical parameters but utilizes a TSSOP-5 package instead of SC-74A-5. Verify pinout compatibility and thermal characteristics before substitution. Other family members may offer different package options but must match the AHCT logic level and AEC-Q100 qualification.
