74LVC2G240GS,115

Overview

The Nexperia 74LVC2G240GS,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 utilizes Schmitt trigger inputs for high noise immunity and includes IOFF circuitry to prevent backflow current during partial power-down states. It is housed in an XSON8 package (SOT1203) measuring 1.35 x 1.0 x 0.35 mm.

Feature Summary

• Dual inverting buffers with independent three-state output control via active-low enable pins
• Schmitt trigger action on all inputs provides tolerance for slow rise and fall times
• IOFF circuitry disables outputs to prevent damaging backflow current when powered down
• Inputs accept voltages up to 5 V, allowing translation between mixed 3.3 V and 5 V environments

Applications

• Mixed 3.3 V and 5 V logic level translation
• Partial power-down applications requiring backflow current prevention
• High-noise immunity signal buffering in digital systems

Selection Notes

Select this part for designs requiring dual-channel inversion with tri-state capability in a minimal footprint. Ensure the application environment stays within the specified -40 °C to +125 °C temperature range. Confirm that the 1.35 x 1.0 mm XSON8 package dimensions fit the PCB layout constraints. Validate that input signals do not exceed the 5.5 V absolute maximum rating under any operating condition.

Part Context

This device belongs to the 74LVC family of low-voltage CMOS logic components manufactured by Nexperia. The LVC series is designed for operation across a wide voltage spectrum from 1.65 V to 5.5 V, bridging older 5 V logic standards with modern low-power systems. The 74LVC2G240 specifically addresses the need for buffered, inverted signals with high-impedance states in compact electronic assemblies.
