74AHCT1G79GW,165

Overview

The Nexperia 74AHCT1G79GW,165 is a single positive-edge triggered D-type flip-flop housed in a 5-TSSOP package. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum clock frequency of 90 MHz. The device features non-inverting outputs with symmetrical propagation delays of 8 ns at 5 V with 50 pF load. It includes overvoltage tolerant inputs up to 5.5 V, ensuring compatibility in mixed-voltage environments. Static current consumption is specified at 1 µA, and the component is rated for an operating temperature range of -40 °C to +125 °C.

Feature Summary

• Positive-edge triggered D-type flip-flop functionality
• Overvoltage tolerant inputs for mixed-voltage interfacing
• High noise immunity with low power dissipation
• ESD protection exceeding 2000 V (HBM) and 1000 V (CDM)

Applications

• Data storage and register applications
• Signal synchronization circuits
• Mixed-voltage logic translation interfaces

Procurement Notes

Verify that the ordering suffix matches '165' to ensure the correct tape-and-reel packaging configuration. Confirm that the AEC-Q100 qualification status aligns with automotive application requirements if applicable. Cross-reference the manufacturer part number with official distributor catalogs to validate authenticity and avoid counterfeit components. Ensure input voltage levels remain within the specified 4.5 V to 5.5 V range during operation.

Selection Notes

Select this component when TTL-compatible input levels are required alongside CMOS output performance. The AHCT series provides noise immunity suitable for industrial environments. Consider the 5-TSSOP package dimensions for PCB layout constraints. Verify that the 90 MHz clock frequency meets system timing requirements. Evaluate the 8 mA output drive capability against load conditions.

Part Context

This part belongs to the Nexperia 74AHCT1G79 family of single D-type flip-flops. It shares functional characteristics with the 74AHC1G79 but differs in input threshold levels, adhering to TTL standards rather than CMOS. The device is designed for high-speed digital applications requiring reliable data storage and transfer. It complements other logic families by providing robust interface capabilities between different voltage domains.

Replacement Considerations

The parameter-equivalent substitute is the 74AHCT1G79GW,125. Both parts share identical electrical specifications and logical functions. Verify package compatibility and ordering suffix differences before substitution.
