74LVC2G240GT,115

Overview

The Nexperia 74LVC2G240GT,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 (SOT833-1) measuring 1 × 1.95 × 0.5 mm.

Feature Summary

• Features three-state outputs that enter a high-impedance OFF-state when the output enable inputs are set HIGH.
• Incorporates Schmitt trigger action at all inputs to ensure tolerance against slow input rise and fall times.
• Includes dedicated IOFF circuitry to disable outputs and prevent damaging backflow currents when the device is powered down.

Applications

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

Part Context

This component belongs to the 74LVC family of CMOS logic devices, designed for low-voltage operation across various industrial and consumer applications. The GT suffix specifically denotes the XSON8 plastic extremely thin small outline package (SOT833-1), which provides a leadless surface-mount solution optimized for space-constrained printed circuit board designs.

Replacement Considerations

Compatible pinout alternatives include the 74LVC2G240DC, 74LVC2G240DP, 74LVC2G240GN, and 74LVC2G240GS. These variants share identical electrical specifications but differ in physical package type and dimensions.

FAQ

How does the device handle partial power-down conditions?

The 74LVC2G240GT,115 contains IOFF circuitry that automatically disables the outputs when the device is powered down, preventing damaging backflow current through the component.

What is the function of the 1OE and 2OE pins?

Pins 1OE and 2OE are active-low output enable inputs. When these pins are driven HIGH, the corresponding outputs (1Y and 2Y) assume a high-impedance OFF-state.
