74LVC257ABQ,115

Signal Switches, Multiplexers, Decoders Overview

The Nexperia 74LVC257ABQ,115 is a quad 2-input multiplexer with 3-state outputs housed in a DHVQFN16 package (SOT763-1). It operates on a supply voltage range of 1.2 V to 3.6 V and features inputs tolerant up to 5.5 V. The device includes Schmitt-trigger inputs for noise immunity and IOFF circuitry for partial power-down protection. Propagation delays vary from 1.0 ns to 16 ns depending on the voltage level.

Signal Switches, Multiplexers, Decoders Feature Summary

• Features overvoltage tolerant inputs capable of handling signals up to 5.5 V while operating at lower supply voltages.
• Includes IOFF circuitry that disables outputs to prevent damaging backflow currents during partial power-down states.
• Schmitt-trigger action on all inputs ensures tolerance for slower input rise and fall times.

Signal Switches, Multiplexers, Decoders Applications

• Translating signals between mixed 3.3 V and 5 V environments
• Selecting data sources in digital logic circuits
• Routing signals in systems requiring 3-state output control

Signal Switches, Multiplexers, Decoders Selection Notes

This component is part of the LVC logic family designed for low-power applications. Selection should consider the DHVQFN16 package constraints and the requirement for 5 V tolerant I/O if interfacing with higher voltage domains. Ensure the design accounts for the specified temperature range and ESD protection levels.
