74LVC157APW/AUJ

Signal Switches, Multiplexers, Decoders Overview

The NXP USA Inc. 74LVC157APW/AUJ is a quad 2-input multiplexer from the LVC logic family, manufactured by Nexperia B.V. It features four independent data selectors controlled by a common select input (S) and an active LOW enable input (E). The device operates within a wide supply voltage range of 1.2 V to 3.6 V and includes Schmitt-trigger inputs for noise tolerance. It supports overvoltage tolerant inputs up to 5.5 V, allowing direct interfacing with 3.3 V or 5 V devices in mixed-voltage applications.

Signal Switches, Multiplexers, Decoders Feature Summary

• Quad 2-input multiplexer architecture with common select and enable control
• Overvoltage tolerant inputs up to 5.5 V for mixed-voltage translation
• Schmitt-trigger action at all inputs for improved noise immunity
• Direct interface capability with TTL levels

Signal Switches, Multiplexers, Decoders Applications

• Translating signals between mixed 3.3 V and 5 V logic systems
• Moving data from two groups of registers to four common output buses
• Implementing function generators for irregular logic designs

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify that the specific suffix AUJ corresponds to the TSSOP-16 package (SOT403-1) as documented for the base part number 74LVC157APW. Confirm the operating temperature range matches your system requirements, as the datasheet specifies availability from -40 °C to +125 °C. Ensure ESD protection specifications meet your handling standards before finalizing procurement.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a quad multiplexer with low power CMOS consumption is required. It is suitable for applications needing direct interface with TTL levels or operation across a wide voltage range. Consider the TSSOP-16 package if space constraints allow for its dimensions. Verify that the input transition rates comply with the specified limits for your target supply voltage.

Signal Switches, Multiplexers, Decoders Part Context

This component belongs to the 74LVC157A series, which encompasses various package options including SO16, DHVQFN16, and DHXQFN16. The APW designation specifically identifies the plastic thin shrink small outline package variant. The series is designed for general-purpose digital logic applications requiring high-speed data selection with low power dissipation.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Compatible substitutes include other 74LVC157 variants from manufacturers such as Texas Instruments (e.g., SN74LVC157ANSR) or Nexperia (e.g., 74LVC157AD). Ensure the replacement maintains the same logic function, pinout compatibility, and electrical characteristics, particularly the supply voltage range and propagation delay specifications.
