74LVC157AD,112

Signal Switches, Multiplexers, Decoders Overview

The Nexperia 74LVC157AD,112 is a quad 2-input multiplexer in the LVC logic series. It features four independent data channels with a common select input (S) and an active LOW enable input (E). The device operates within a supply voltage range of 1.2 V to 3.6 V and supports overvoltage tolerant inputs up to 5.5 V. It utilizes Schmitt-trigger action for noise immunity and is housed in a 16-lead SO plastic small outline package (SOT109-1).

Signal Switches, Multiplexers, Decoders Feature Summary

• Quad 2-input multiplexer architecture with common selector and enable control.
• Overvoltage tolerant inputs allowing direct interfacing with 5 V logic devices.
• Schmitt-trigger inputs provide tolerance for slower rise and fall times.
• CMOS construction ensures low power consumption across the operating voltage range.

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 highly irregular logic functions using two variables.

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering suffix '112' against the manufacturer's current documentation to confirm the exact tape-and-reel packaging configuration. Ensure the selected package variant matches the required PCB footprint and thermal dissipation constraints for the target application environment.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a quad multiplexer with high-speed switching and wide voltage compatibility is required. The LVC series offers superior performance compared to standard CMOS logic while maintaining low power characteristics suitable for battery-operated or energy-efficient designs.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the 74LVC157A family of quad multiplexers manufactured by Nexperia USA Inc. The 'AD' designation identifies the SO16 plastic small outline package (SOT109-1), which provides a compact surface-mount solution for high-density circuit board layouts.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Compatible substitutes include other 74LVC157 variants such as the TSSOP16 version (74LVC157APW) or DHVQFN16 version (74LVC157ABQ), provided the package dimensions are compatible with the existing design.
