74LVC2G240DC-Q100H

Overview

The Nexperia 74LVC2G240DC-Q100H is a dual inverting buffer and line driver featuring three-state outputs, housed in an SOT765-1 VSSOP8 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 includes Schmitt trigger inputs for noise immunity and IOFF circuitry for partial power-down protection. Qualified to AEC-Q100 Grade 1 standards, it functions reliably from -40 °C to +125 °C.

Feature Summary

• Dual-channel inverting buffers with independent three-state output control via active-low enable inputs.
• Schmitt trigger action on all inputs provides high tolerance for slow rise and fall times.
• IOFF circuitry prevents damaging backflow currents during partial power-down conditions.
• Inputs accept voltages up to 5.5 V, enabling direct interfacing between 3.3 V and 5 V logic systems.

Applications

• Automotive electronic systems requiring AEC-Q100 Grade 1 qualification.
• Mixed-signal environments translating signals between 3.3 V and 5 V logic levels.
• Partial power-down applications utilizing IOFF functionality to isolate powered-down sections.

Procurement Notes

Verify the specific suffix DC corresponds to the VSSOP8 (SOT765-1) package variant when sourcing. Confirm that the required operating temperature range aligns with the specified -40 °C to +125 °C limits. Ensure design safeguards account for the absolute maximum ratings regarding supply voltage and output current to prevent permanent device damage.

Selection Notes

Select this component for designs requiring dual-channel inversion with bus isolation capabilities. The wide supply voltage compatibility allows flexibility in system architecture. Consider the VSSOP8 package dimensions for PCB layout constraints. Verify that the propagation delay characteristics meet the timing requirements of the target application interface.

Part Context

This part belongs to the Nexperia 74LVC2G240-Q100 family of automotive-grade logic devices. It shares functional similarities with other LVC series buffers but is distinct due to its specific AEC-Q100 qualification and three-state output configuration. The DC suffix identifies the plastic very thin shrink small outline package variant.

Replacement Considerations

Direct substitutes include the 74LVC2G240DP-Q100H, which offers identical electrical performance in a TSSOP8 package. Other compatible alternatives within the same family may be considered if pinout and package form factors are adjusted accordingly.
