74AUP1G157GF,132

Overview

The 74AUP1G157GF,132 is a single 2-input multiplexer from the Nexperia AUP logic family. It operates within a supply voltage range of 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 and includes IOFF circuitry for partial power-down applications. Static power consumption is low, with ICC maximums ranging from 0.5 µA at 25 °C to 1.4 µA at elevated temperatures. Propagation delay varies by voltage, typically between 2.2 ns and 19.9 ns depending on load capacitance and supply level.

Feature Summary

• Schmitt trigger action at all inputs provides tolerance to slower input rise and fall times.
• IOFF circuitry disables outputs during power-down to prevent damaging backflow currents.
• CMOS construction ensures very low static and dynamic power consumption across the entire voltage range.
• Overvoltage tolerant inputs allow operation with signals up to 3.6 V regardless of the supply voltage.

Applications

• Partial power-down mode operations requiring backflow current prevention
• Signal routing in mixed-voltage systems with slow transition inputs
• Low-power data selection circuits in portable electronic devices

Procurement Notes

Verify that the GF suffix corresponds to the specific XSON6 package variant required for your design, as the datasheet lists multiple XSON6 packages (GM, GN, GS, GX). Confirm the manufacturer is Nexperia, as NXP USA Inc. may distribute or rebrand these components. Ensure the operating environment stays within the specified -40 °C to +125 °C range to maintain electrical characteristics.

Selection Notes

Select this component when low power dissipation and high noise immunity are critical. The wide supply voltage range makes it suitable for battery-powered applications. Verify that the specific GF package dimensions fit the PCB footprint, as the AUP1G157 series offers several distinct leadless packages with different thermal and mechanical properties.

Part Context

This part belongs to the 74AUP1G157 series of low-power 2-input multiplexers manufactured by Nexperia. The series is designed for applications requiring minimal power consumption and robust signal integrity. The AUP family is characterized by its ability to operate at low voltages while maintaining high-speed performance relative to other low-voltage logic families.

Replacement Considerations

Check for other 74AUP1G157 variants with different package codes such as GM, GN, GS, or GX if the GF package is unavailable. Ensure any substitute maintains the same AUP logic family characteristics and voltage range. Automotive qualified versions like the 74AUP1G157-Q100 exist but require separate qualification verification.
