74LVC1G240GXH

Overview

The Nexperia 74LVC1G240GXH is a single inverting buffer and line driver with three-state outputs, housed in an X2SON5 (SOT1226-3) package. It operates within a supply voltage range of 1.65 V to 5.5 V and supports input voltages up to 5.5 V. The device features Schmitt-trigger inputs for noise immunity and IOFF circuitry for partial power-down protection. It provides ±24 mA output drive capability at 3.0 V and complies with JEDEC standards JESD8-7, JESD8-5, JESD8C, and JESD36.

Feature Summary

• Features Schmitt-trigger inputs to tolerate slower rise and fall times
• Includes IOFF circuitry to prevent damaging backflow current during partial power-down
• Provides high noise immunity and direct interface with TTL levels
• Supports overvoltage tolerant inputs up to 5.5 V

Applications

• Mixed 3.3 V and 5 V environments
• Partial power-down applications
• Line driving and buffering

Procurement Notes

Verify the specific ordering suffix GXH corresponds to the X2SON5 package variant when sourcing. Confirm that the component meets RoHS compliance requirements for your region. Ensure design-in processes account for the thermal characteristics specific to the SOT1226-3 package outline provided in the datasheet.

Selection Notes

Select this component for designs requiring a single-channel inverting buffer with three-state control in a compact footprint. The X2SON5 package offers thermal enhancement suitable for space-constrained PCB layouts. Ensure the application voltage remains within the 1.65 V to 5.5 V operating range to maintain specified performance levels.

Part Context

This part belongs to the 74LVC family of low-voltage CMOS logic devices manufactured by Nexperia. The 74LVC1G240 series includes multiple package options such as TSSOP5, XSON6, and X2SON5. The GXH suffix specifically identifies the X2SON5 version, which is designed for high-density surface-mount applications.

Replacement Considerations

Direct replacements include other packages of the same logical function, such as 74LVC1G240GW or 74LVC1G240GM. Verify pin compatibility and thermal dissipation requirements when substituting between different package types within the same product family.
