74AUP2G157GS,115

Overview

The Nexperia 74AUP2G157GS,115 is a low-power 2-input multiplexer housed in an XSON8 package (SOT1203). It selects data from two inputs (I0, I1) based on a common select input (S), providing true and complement outputs. The device operates with a supply voltage range of 0.8 V to 3.6 V and features Schmitt trigger inputs for noise tolerance. It supports partial power-down via IOFF circuitry and complies with JEDEC standards for various voltage levels.

Feature Summary

• Schmitt trigger action at all inputs ensures tolerance to slower rise and fall times across the entire operating voltage range.
• IOFF circuitry enables partial power-down mode by disabling outputs to prevent damaging backflow currents when powered down.
• High noise immunity with low overshoot and undershoot characteristics relative to the supply voltage.
• Robust ESD protection exceeding specified thresholds for both Human Body Model and Charged Device Model standards.

Applications

• Partial power-down applications requiring isolation during power-off states
• Signal routing in low-voltage digital systems
• Data selection circuits in portable battery-operated devices

Procurement Notes

Verify the specific ordering suffix '115' against official Nexperia documentation to confirm tape-and-reel packaging specifications. Ensure the SOT1203 package variant matches design footprint requirements. Cross-reference the revision history to confirm compliance with current JEDEC ESD standards before finalizing procurement orders.

Selection Notes

Select this component for designs requiring a single 2-input multiplexer with complementary outputs in a compact XSON8 form factor. Consider the 0.8 V to 3.6 V operating range for compatibility with low-voltage logic families. Verify that the thermal derating characteristics for the SOT1203 package meet the ambient temperature constraints of the target application environment.

Part Context

This part belongs to the 74AUP2G157 family of low-power 2-input multiplexers manufactured by Nexperia. The GS suffix specifically denotes the XSON8 package type (SOT1203) with dimensions of 1.35 mm x 1.0 mm x 0.35 mm. The family shares functional similarities but differs in physical package options such as VSSOP8 and other XSON variants.

Replacement Considerations

Direct substitutes include other 74AUP2G157 variants in different packages, such as 74AUP2G157DC (VSSOP8), 74AUP2G157GT (XSON8 SOT833-1), or 74AUP2G157GN (XSON8 SOT1116), provided the PCB footprint allows for package adaptation.
