74AXP1G157GSH

Overview

The Nexperia 74AXP1G157GSH is a single 2-input multiplexer housed in an XSON6 (SOT1202) package. It selects data from inputs I0 or I1 based on the state of the common select input S, presenting the result at output Y. The device operates within a supply voltage range of 0.7 V to 2.75 V and supports partial power-down via IOFF circuitry. Propagation delay ranges from 0.9 ns to 138 ns depending on voltage and load.

Feature Summary

• Schmitt-trigger action provides tolerance for slow input transitions
• IOFF circuitry prevents backflow current during partial power-down
• Low input and output capacitance minimizes signal loading effects
• High noise immunity with low overshoot and undershoot characteristics

Applications

• Battery-powered portable electronics requiring ultra-low static power
• Partial power-down systems needing safe isolation when powered off
• Signal routing in mixed-voltage logic environments
• Data selection circuits in space-constrained mobile devices

Procurement Notes

Verify the specific suffix GSH corresponds to the XSON6 SOT1202 package variant before ordering. Confirm that the application environment remains within the specified -40 °C to +85 °C temperature range. Ensure supply voltage does not exceed 2.75 V during active operation to maintain reliability standards defined in the datasheet.

Selection Notes

Select this component for designs prioritizing minimal footprint and ultra-low power consumption over high-speed switching. The wide operating voltage range allows compatibility with various low-voltage logic families. Consider the propagation delay variations across different supply voltages when designing timing-critical paths.

Part Context

This device belongs to the Nexperia AXP logic family, designed for advanced low-power applications. It utilizes Advanced BiCMOS Technology to achieve performance levels suitable for battery-operated devices. The XSON6 package offers a compact solution for modern PCB miniaturization requirements while maintaining robust electrical characteristics.

Replacement Considerations

Check for other variants within the 74AXP1G157 series such as GM or GN if package dimensions differ. Verify functional equivalence with other single 2-input multiplexers if pinout compatibility is required. Ensure any substitute maintains the same IOFF functionality and voltage specifications.
