74AUP1G157GW,125

Overview

The Nexperia 74AUP1G157GW,125 is a single 2-input multiplexer in the AUP logic series. It operates within a supply voltage range of 0.8 V to 3.6 V and supports an ambient temperature range from -40 °C to +125 °C. The device utilizes Schmitt trigger inputs for noise tolerance and includes IOFF circuitry for partial power-down applications. It is housed in a TSSOP6 (SOT363-2) package with six leads.

Feature Summary

• Schmitt trigger action at all inputs provides tolerance to slower input rise and fall times.
• IOFF circuitry disables the output during power-down to prevent damaging backflow current.
• CMOS construction ensures very low static and dynamic power consumption across the entire supply voltage range.

Applications

• Partial power-down mode operation
• Signal routing in mixed-voltage systems
• Data selection circuits

Procurement Notes

Verify that the ordering suffix matches the required package type. Confirm the specific temperature grade aligns with system requirements. Check for any recent Product Change Notifications regarding marking or assembly updates. Ensure compliance with JEDEC standards relevant to the target operating voltage range.

Selection Notes

Select this component when a single 2-input multiplexer is required in a space-constrained design. The TSSOP6 package offers a compact footprint suitable for surface-mount assembly. Consider the wide supply voltage range if interfacing with varying logic levels. Verify that the low power dissipation meets the thermal budget of the application.

Part Context

This part belongs to the 74AUP1Gxx family of single-function logic devices. The AUP series is characterized by low power consumption and high noise immunity. The GW suffix specifically denotes the TSSOP6 plastic thin shrink small outline package variant manufactured by Nexperia.

Replacement Considerations

Direct substitutes include other 74AUP1G157 variants such as 74AUP1G157GM, 74AUP1G157GN, 74AUP1G157GS, and 74AUP1G157GX, provided the package form factor is acceptable for the PCB layout.
