74LVC257APW,118

Signal Switches, Multiplexers, Decoders Overview

The Nexperia 74LVC257APW,118 is a quad 2-input multiplexer with 3-state outputs housed in a TSSOP16 package. It operates on a supply voltage range of 1.2 V to 3.6 V and features inputs tolerant up to 5.5 V. Propagation delays vary from 1.0 ns to 16 ns depending on voltage. The device supports Schmitt-trigger inputs and includes IOFF circuitry for partial power-down applications.

Signal Switches, Multiplexers, Decoders Feature Summary

• Provides 5 V tolerant inputs and outputs for mixed voltage environments
• Includes IOFF circuitry to prevent backflow current during power-down
• Features Schmitt-trigger action at all inputs for noise tolerance

Signal Switches, Multiplexers, Decoders Applications

• Mixed 3.3 V and 5 V system translation
• Partial power-down mode operation
• Data routing in low-voltage logic circuits

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific suffix '118' corresponds to the TSSOP16 (SOT403-1) package variant. Confirm RoHS compliance and REACH status against the latest manufacturer documentation before integration. Ensure design accounts for the specified thermal derating characteristics above 91 °C.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when interfacing between 3.3 V and 5 V logic domains is required. The wide supply range allows operation down to 1.2 V. Verify that the TSSOP16 footprint matches the PCB layout constraints and that the 3-state output enable requirements align with the system bus architecture.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the 74LVC257A family of quad multiplexers. It shares functional specifications with other packages like SO16 (74LVC257AD) and DHVQFN16 (74LVC257ABQ), differing only in physical housing dimensions and lead configuration while maintaining identical electrical performance profiles.
