74LVC1G79GMH

Overview

The 74LVC1G79GMH is a single positive-edge triggered D-type flip-flop manufactured by Nexperia (formerly NXP). It operates within a supply voltage range of 1.65 V to 5.5 V, ensuring compatibility with mixed 3.3 V and 5 V environments. The device features inputs that accept voltages up to 5 V, allowing direct interfacing with TTL levels. It includes I_OFF circuitry for partial power-down applications, preventing damaging backflow current. The component supports output drive currents of ±24 mA at 3.0 V and offers high noise immunity.

Feature Summary

• Single positive-edge triggered D-type flip-flop functionality
• Wide operating voltage range from 1.65 V to 5.5 V
• I_OFF circuitry enables partial power-down mode protection
• Inputs tolerate up to 5 V for mixed-voltage system integration

Applications

• Test and measurement equipment
• Telecommunications infrastructure
• Personal electronics devices
• White home appliances

Procurement Notes

Verify the specific suffix 'GMH' against official Nexperia documentation to confirm package type and tape/reel specifications. Ensure the source document explicitly lists this exact part number variant, as distributors may list generic family members like 74LVC1G79GW or 74LVC1G79GV. Confirm RoHS compliance status and moisture sensitivity level directly from the manufacturer's datasheet before procurement.

Selection Notes

Select this component when a single-bit storage element with positive-edge triggering is required in low-power designs. It is suitable for systems requiring operation across a wide voltage spectrum from 1.65 V to 5.5 V. The built-in I_OFF feature makes it appropriate for applications needing protection against backflow current during partial power-down states. Ensure input voltage levels do not exceed the maximum rating for reliable operation.

Part Context

This device belongs to the 74LVC logic family, characterized by CMOS low power consumption and high-speed performance. It is part of the single-function gate series designed for general-purpose digital applications. The product line supports various small surface-mount packages, facilitating compact PCB layouts for modern electronic devices requiring efficient space utilization.

Replacement Considerations

Public confirmed substitutes include 74LVC1G79GW,125 and SN74LVC1G79. Verify pinout compatibility and electrical characteristics such as propagation delay and output drive current before substitution.
