74AUP1G157GXZ

Overview

The Nexperia 74AUP1G157GXZ is a low-power 2-input multiplexer housed in an X2SON6 (SOT1255-2) package. It operates on a single supply voltage ranging from 0.8 V to 3.6 V and supports an ambient temperature range of -40 °C to +125 °C. The device features Schmitt trigger inputs for noise tolerance, IOFF circuitry for partial power-down applications, and high ESD protection exceeding 5000 V HBM.

Feature Summary

• Schmitt trigger action at all inputs provides tolerance to slower input rise and fall times.
• IOFF circuitry disables the output to prevent damaging backflow current during partial power-down mode.
• CMOS construction ensures very low static and dynamic power consumption across the entire supply voltage range.

Applications

• Partial power-down applications requiring backflow current prevention
• Mixed-signal systems with slow input transition rates
• Low-voltage logic circuits operating between 0.8 V and 3.6 V

Procurement Notes

Verify the specific ordering suffix 'Z' against the manufacturer's official documentation to confirm packaging details such as reel specifications or tape-and-reel dimensions. Ensure the component matches the X2SON6 (SOT1255-2) physical outline before integration into the design.

Selection Notes

Select this component when a compact thermal-enhanced package is required for low-power signal routing. The wide supply voltage range accommodates various logic families, while the Schmitt trigger inputs simplify interface design with noisy or slow signals.

Part Context

This part belongs to the 74AUP series of advanced ultra-low power logic devices. The GX variant specifically utilizes the X2SON6 package, which offers a small footprint with enhanced thermal dissipation capabilities compared to standard plastic packages in the same family.

Replacement Considerations

Direct replacements include other 74AUP1G157 variants with different packages, such as 74AUP1G157GM (XSON6), 74AUP1G157GW (TSSOP6), or 74AUP1G157GN (XSON6). Verify pinout compatibility and thermal requirements when substituting.
