74AUP1G158GW,125

Overview

The 74AUP1G158GW,125 is a single low-power 2-input inverting multiplexer from the Nexperia AUP logic family. It operates within a supply voltage range of 0.8 V to 3.6 V and features Schmitt-trigger inputs for noise tolerance. The device includes I_OFF circuitry to prevent backflow current during partial power-down states. It is housed in a 6-lead TSSOP surface-mount package and supports operating temperatures from -40 °C to +125 °C.

Feature Summary

• Single 2-input inverting multiplexer with high noise immunity
• Schmitt-trigger action at all inputs for slower rise/fall time tolerance
• I_OFF circuitry enables safe partial power-down mode operation
• Wide supply voltage compatibility across multiple JEDEC standards

Applications

• Data routing in portable battery-powered devices
• Signal selection in low-voltage embedded systems
• Input multiplexing for microcontroller peripheral management

Procurement Notes

Verify the specific suffix '125' corresponds to the tape-and-reel packaging configuration required for your assembly line. Confirm that the TSSOP-6 footprint matches your PCB design guidelines. Ensure compliance with RoHS directives as indicated by the manufacturer specifications before finalizing procurement orders.

Selection Notes

Select this component when a single-channel 2-to-1 signal path with inversion is required in space-constrained designs. The AUP series offers superior speed-to-power efficiency compared to older logic families. Consider the TSSOP-6 package dimensions against available board real estate and thermal dissipation requirements for the target application environment.

Part Context

This part belongs to the 74AUP1Gxx series of single-function logic ICs designed for ultra-low power consumption. The AUP family utilizes advanced CMOS technology to achieve high switching speeds while maintaining minimal static current draw. These components are engineered for modern portable electronics where battery life and signal integrity are critical constraints.

Replacement Considerations

Direct substitutes include other single 2-input inverting multiplexers in TSSOP-6 packages from compatible logic families, provided voltage ranges and pin configurations align. Verify functional equivalence regarding propagation delay and input threshold characteristics before substitution.
