74AHCT1G79GW,125

Overview

The Nexperia 74AHCT1G79GW,125 is a single positive-edge triggered D-type flip-flop in the 74AHCT logic series. It operates on a supply voltage of 4.5V to 5.5V with a maximum clock frequency of 90 MHz. The device features TTL-compatible input levels and non-inverting outputs capable of sourcing and sinking 8mA. Key electrical parameters include a propagation delay of 8ns at 5V with 50pF load, static current of 1µA, and input capacitance of 1.5 pF. It is housed in a 5-TSSOP package and rated for operation between -40°C and +125°C.

Feature Summary

• Positive-edge triggered D-type flip-flop functionality
• TTL-compatible input levels for direct interface with TTL systems
• Overvoltage tolerant inputs allowing use in mixed voltage environments
• High noise immunity with low power dissipation characteristics

Applications

• Data storage and register applications
• Signal synchronization and timing control
• Parallel-to-serial data conversion circuits
• State machine implementation in digital logic designs

Procurement Notes

Verify the specific ordering suffix '125' to confirm the tape and reel packaging configuration. Ensure compatibility with standard surface-mount assembly processes for the 5-TSSOP package. Confirm that the 4.5V to 5.5V supply range aligns with the target system design requirements before finalizing procurement.

Selection Notes

Select this component when TTL-level input compatibility is required within a CMOS logic family. It serves as an alternative to the 74AHC1G79 when interfacing with legacy TTL signals. Consider the 8ns propagation delay and 90 MHz clock limit for high-speed timing constraints. Verify that the 5-TSSOP footprint fits the available PCB space.

Part Context

This part belongs to the Nexperia 74AHCT1Gxx series of single-function logic devices. It shares the same pinout and functional behavior as the 74AHCT1G79 but is distinguished by the '125' suffix indicating specific packaging and handling specifications. It complements other single-gate or flip-flop variants in the 74AHCT family for compact digital circuit designs.

Replacement Considerations

The 74AHCT1G79GW is listed as a parameter-equivalent substitute. Designers should verify that the replacement part maintains identical packaging and electrical characteristics to ensure seamless integration without schematic modifications.
