74LVC2G240GF,115

Overview

The Nexperia 74LVC2G240GF,115 is a dual inverting buffer and line driver featuring three-state outputs controlled by active-low enable inputs (1OE, 2OE). It operates within a supply voltage range of 1.65 V to 5.5 V and supports input voltages up to 5 V, enabling direct interfacing with 3.3 V or 5 V logic devices. The component includes Schmitt trigger action at all inputs for high noise immunity against slow signal transitions. It incorporates IOFF circuitry to disable outputs during partial power-down, preventing damaging backflow currents. The device complies with JEDEC standards JESD8-7, JESD8-5, and JESD8-B/JESD36.

Feature Summary

• Features three-state outputs that enter a high-impedance OFF-state when the output enable inputs are HIGH.
• Incorporates Schmitt trigger inputs to provide high tolerance for slower input rise and fall times.
• Includes dedicated IOFF circuitry to prevent damaging backflow current during partial power-down applications.

Applications

• Mixed 3.3 V and 5 V logic environments
• Partial power-down systems requiring backflow prevention
• Interfaces requiring high noise immunity

Procurement Notes

Verify the specific package designation associated with the GF suffix, as the official product data sheet revision history indicates this type number was removed from the standard listing. Confirm availability through Nexeria sales channels rather than relying on generic distributor stock lists. Ensure the selected variant matches the required thermal and mechanical specifications for the target application.

Selection Notes

Select this component when a dual inverting buffer with three-state control is required for mixed-voltage logic translation. The wide supply voltage range allows operation across various low-power digital systems. Verify that the input transition rates remain within specified limits to ensure proper Schmitt trigger functionality and noise immunity.

Part Context

This part belongs to the 74LVC family of CMOS logic devices, designed for low-voltage applications. The 74LVC2G240 series provides dual buffering capabilities in compact packages. While the GF variant is referenced in ordering information, it has been removed from recent datasheet revisions, indicating potential discontinuation or replacement by other package options like GS or GT.

Replacement Considerations

Public confirmed substitute part numbers: 74LVC2G240GS,115; 74LVC2G240GT,115; 74LVC2G240DP,125; 74LVC2G240DC,125.
