74AUP1G157GS,132

Overview

The 74AUP1G157GS,132 is a single 2-input multiplexer from the Nexperia AUP series. It operates within a supply voltage range of 0.8 V to 3.6 V and features Schmitt trigger inputs for noise immunity. The device supports partial power-down via IOFF circuitry and complies with JEDEC standards. It is housed in an XSON-6 package (SOT1202) with dimensions of 1.0 x 1.0 x 0.35 mm. Propagation delay ranges from 1.9 ns to 7.7 ns depending on load capacitance and voltage.

Feature Summary

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

Applications

• Partial power-down applications requiring controlled output states during power-off.
• Systems utilizing slow input signal transitions where noise immunity is critical.
• Low-power portable electronics operating within the 0.8 V to 3.6 V supply range.

Selection Notes

Select this component when a single 2-input multiplexer is required in a space-constrained design. The XSON-6 package offers a small footprint suitable for dense PCB layouts. Ensure the application voltage remains within the 0.8 V to 3.6 V range to maintain specified performance characteristics and avoid exceeding absolute maximum ratings.

Part Context

This part belongs to the 74AUP1Gxx family of single-function logic devices. The GS suffix denotes the XSON-6 package (SOT1202), which is distinct from other variants like GM or GX. It is designed for low-voltage digital applications requiring high noise immunity and low power dissipation.

Replacement Considerations

Direct pin-compatible replacements include other packages of the same function such as 74AUP1G157GM or 74AUP1G157GX. Verify package dimensions and thermal requirements when substituting between different XSON variants.
