74AXP1G157GNH

Overview

The Nexperia 74AXP1G157GNH is a single 2-input multiplexer housed in an XSON6 package (SOT1115). 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 with a supply voltage range of 0.7 V to 2.75 V and includes Schmitt-trigger inputs for noise tolerance. It features IOFF circuitry for partial power-down applications, preventing backflow current when powered down.

Feature Summary

• Schmitt-trigger action at all inputs provides tolerance for slower input rise and fall times.
• IOFF circuitry enables partial power-down mode by disabling the output to prevent damaging backflow currents.
• Low input and output capacitance supports high-speed signal integrity.
• Complies with multiple JEDEC standards across various voltage ranges.

Applications

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

Procurement Notes

Verify the specific suffix GN corresponds to the XSON6 SOT1115 package variant as listed in the ordering information table. Confirm that the required temperature range of -40°C to +85°C aligns with your application environment. Ensure design compatibility with the specified supply voltage limits and input voltage thresholds defined in the recommended operating conditions section of the datasheet.

Selection Notes

Select this component for applications requiring a single-channel multiplexer with ultra-low static power consumption. The wide supply voltage range allows operation in diverse low-power environments. Verify that the package dimensions of the XSON6 SOT1115 fit within the available PCB space constraints. Consider the propagation delay characteristics relative to the system clock speed requirements.

Part Context

This device belongs to the 74AXP1G series of single logic gates and multiplexers designed for low-voltage applications. The 74AXP1G157 specifically functions as a 2-to-1 multiplexer. It is part of Nexperia's portfolio aimed at reducing power consumption in portable electronics while maintaining signal integrity through Schmitt-trigger inputs and low capacitance profiles.

Replacement Considerations

Check for other variants within the 74AXP1G157 family, such as GM (SOT886) or GS (SOT1202), if package footprint changes are permissible. Ensure any substitute maintains the same functional logic, voltage range, and IOFF capabilities.
