74LVC2G240DP,125

Overview

The Nexperia 74LVC2G240DP,125 is a dual inverting buffer and line driver featuring three-state outputs housed in an 8-lead TSSOP plastic thin shrink small outline package (SOT505-2). It operates within a supply voltage range of 1.65 V to 5.5 V and supports input voltages up to 5 V. The device includes Schmitt trigger inputs for noise immunity and IOFF circuitry for partial power-down applications. It functions across an ambient temperature range of -40 °C to +125 °C.

Feature Summary

• Dual inverting buffer/line driver with three-state outputs controlled by active LOW enable inputs
• Schmitt trigger action at all inputs provides high tolerance for slower rise and fall times
• IOFF circuitry disables outputs to prevent damaging backflow current during partial power-down
• Inputs accept voltages up to 5 V, allowing direct interfacing with 3.3 V or 5 V logic devices

Applications

• Mixed 3.3 V and 5 V environments requiring signal translation
• Partial power-down applications utilizing IOFF functionality
• Interfaces requiring high noise immunity and slow input transition tolerance

Procurement Notes

Verify the specific ordering suffix

Selection Notes

Select this component when a compact dual inverting buffer with three-state control is required. The TSSOP8 package suits space-constrained surface mount designs. Ensure the application utilizes the IOFF feature if powering down parts of the system while other sections remain active. Confirm that the 5 V tolerant inputs align with the source logic levels.

Part Context

This part belongs to the 74LVC family of low-voltage CMOS logic. It shares functional characteristics with other variants like the 74LVC2G240DC and 74LVC2G240GT, differing primarily in package type. The DP suffix specifically denotes the TSSOP8 package configuration used for this orderable item.

Replacement Considerations

Direct replacements include 74LVC2G240DC,125 (VSSOP8) and 74LVC2G240GT,125 (XSON8). Verify pinout compatibility and thermal derating requirements as package-specific power dissipation limits differ between TSSOP, VSSOP, and XSON formats.
