74LVC1G240GM,115

Overview

The 74LVC1G240GM,115 is a single inverting buffer and line driver with three-state outputs manufactured by Nexperia. It operates within a supply voltage range of 1.65 V to 5.5 V and features Schmitt-trigger inputs for noise immunity. The device includes an output enable (OE) pin that controls the high-impedance OFF-state. It utilizes IOFF circuitry to prevent backflow current during partial power-down conditions. The component is housed in an XSON6 package (SOT886) and supports operation across temperatures from -40 °C to +125 °C.

Feature Summary

• Provides three-state output control via an active-low OE input signal
• Incorporates IOFF circuitry to disable outputs and prevent damaging backflow currents when powered down
• Features Schmitt-trigger action at all inputs to tolerate slower rise and fall times

Applications

• Translating signals between mixed 3.3 V and 5 V logic environments
• Driving capacitive loads in bus-oriented systems
• Clock distribution and buffering applications requiring high noise immunity

Procurement Notes

Verify the specific ordering suffix matches the required package type, as the base part number covers multiple packages including TSSOP5 and X2SON5. Confirm the temperature grade corresponds to the application requirements, noting that the GM variant specifies the -40 °C to +125 °C range. Ensure compliance with RoHS directives and check for any recent product change notices regarding assembly or material updates before finalizing procurement.

Selection Notes

Select this component when a single-channel inverting buffer with three-state capability is required. It is suitable for designs needing direct interface with TTL levels and overvoltage tolerant inputs up to 5.5 V. Consider the XSON6 package dimensions if board space is constrained. Verify that the load capacitance and drive current requirements fall within the specified dynamic and static characteristics for the target operating voltage.

Part Context

This device belongs to the 74LVC family of low-voltage CMOS logic components. The LVC series is designed for general-purpose digital applications requiring wide supply voltage ranges and compatibility with various logic families. The 74LVC1G240 specifically addresses the need for compact, single-function buffers in portable and battery-powered electronics where power consumption and noise tolerance are critical design factors.

Replacement Considerations

The datasheet lists the 74LVC1G240GW (TSSOP5), 74LVC1G240GS (XSON6), and 74LVC1G240GX (X2SON5) as alternative package options for the same logical function. These variants share identical electrical specifications but differ in physical footprint and thermal properties. No cross-manufacturer substitutes are documented in the provided source material.
