74AUP1T34GXH

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74AUP1T34GXH is a single dual supply translating buffer housed in an X2SON5 (SOT1226-3) package. It features Schmitt-trigger inputs for noise immunity and IOFF circuitry for partial power-down support. Supply voltages VCC(A) and VCC(Y) range from 1.1 V to 3.6 V. Static current is 0.9 µA maximum at 25 °C, rising to 1.4 µA at +125 °C. Propagation delay ranges from 2.9 ns to 30.5 ns depending on load capacitance and voltage conditions.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Dual independent supply rails allow translation between different logic voltage levels
• Schmitt-trigger action provides tolerance for slow input rise and fall times
• IOFF circuitry disables outputs to prevent damaging backflow currents during power-down

Buffers, Drivers, Receivers, Transceivers Applications

• Partial power-down mode applications requiring isolation of powered-down ports
• Voltage level translation between mixed-voltage digital systems
• Signal buffering in low-power CMOS designs with varying supply rails

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix GXH corresponds to the X2SON5 package variant when sourcing. Confirm that the required temperature range matches the -40 °C to +125 °C specification. Ensure design compatibility with the 1.1 V to 3.6 V supply voltage limits for both ports A and Y.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a single-channel buffer with independent supply domains is required. The X2SON5 package offers a compact footprint suitable for space-constrained layouts. Verify that the application does not exceed the 250 mW total power dissipation limit under operating conditions.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the 74AUP series of low-power CMOS logic devices. The 'T' designation indicates a translating buffer function with dual supplies. The 'GXH' suffix identifies the specific X2SON5 thermal-enhanced package configuration within the broader 74AUP1T34 product family.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check datasheets for alternative packages like TSSOP5 or XSON6 if pinout compatibility is required. Verify that substitute parts maintain the same dual-supply architecture and IOFF functionality.
