74LVC2G240GM,125

Overview

The Nexperia 74LVC2G240GM,125 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 Schmitt trigger inputs for noise immunity. The device includes IOFF circuitry to prevent backflow current during partial power-down states. It provides high noise immunity and direct interface with TTL levels.

Feature Summary

• Dual inverting buffers with three-state outputs controlled by dedicated enable pins
• Schmitt trigger action at all inputs ensures tolerance for slow rise and fall times
• IOFF circuitry disables outputs to prevent damaging backflow current when powered down

Applications

• Mixed 3.3 V and 5 V logic environments requiring signal translation
• Partial power-down applications utilizing IOFF functionality
• High-noise immunity buffering for digital signals

Procurement Notes

Verify the specific package type against the datasheet ordering information table. The GM suffix corresponds to an XQFN8 package which was removed from the product specification in revision 11 (July 2019). Confirm availability of current equivalent packages such as TSSOP8 or VSSOP8 if the GM variant is discontinued.

Selection Notes

Select this component for designs requiring dual inverting buffers with three-state control. Ensure the application environment supports the specified 1.65 V to 5.5 V supply range. Verify that the required package dimensions match the available versions listed in the current ordering information table.

Part Context

This part belongs to the 74LVC family of low-voltage CMOS logic devices manufactured by Nexperia. The series is designed for applications requiring wide supply voltage ranges and compatibility with both 3.3 V and 5 V systems. The 74LVC2G240 specifically provides dual buffering capabilities.

Replacement Considerations

The 74LVC2G240GM variant was removed from the official product data sheet in July 2019. Current equivalents include 74LVC2G240DP (TSSOP8), 74LVC2G240DC (VSSOP8), 74LVC2G240GT (XSON8), 74LVC2G240GN (XSON8), and 74LVC2G240GS (XSON8).
