74AUP1G19GW,125

Overview

The Nexperia 74AUP1G19GW,125 is a low-power 1-of-2 decoder/demultiplexer housed in a TSSOP6 (SOT363-2) package. It features a common enable input and provides true and complement outputs. The device operates across a wide supply voltage range of 0.8 V to 3.6 V with Schmitt-trigger inputs for noise immunity. Static power consumption is specified at a maximum of 0.9 µA within the -40 °C to +125 °C temperature range.

Feature Summary

• Includes IOFF circuitry to disable outputs during partial power-down, preventing damaging backflow currents
• Schmitt-trigger action on all inputs ensures tolerance for slower rise and fall times
• Inputs are overvoltage tolerant up to 3.6 V regardless of the supply voltage level

Applications

• Partial power-down mode applications requiring safe isolation when powered down
• Signal routing and demultiplexing in low-voltage digital logic systems
• Data distribution circuits utilizing active-low control signals

Procurement Notes

Verify the specific ordering suffix matches the required package type, as the AUP1G19 series is available in multiple configurations including XSON variants. Confirm that the TSSOP6 designation aligns with your board layout requirements. Ensure the selected component meets the necessary environmental specifications for your intended operating temperature range before finalizing procurement.

Selection Notes

Select this component for designs requiring a single-channel decoder with complementary outputs in a minimal footprint. The wide voltage compatibility supports mixed-voltage interfaces without external level shifting. Consider the propagation delay characteristics relative to your system clock speed and load capacitance to ensure signal integrity is maintained under dynamic operating conditions.

Part Context

This part belongs to the Nexperia 74AUP family of ultra-low-power CMOS logic devices. The AUP series is designed for battery-powered applications due to its extended voltage range and reduced static current consumption compared to standard logic families. The 1G prefix indicates a single functional circuit contained within a compact surface-mount package suitable for high-density PCB assembly.

Replacement Considerations

Direct pin-compatible replacements include other 74AUP1G19 variants such as the GM or GN versions if different package footprints are acceptable. Verify that any substitute maintains the same TSSOP6 outline dimensions and electrical characteristics, particularly the IOFF functionality and Schmitt-trigger thresholds.
