74AUP1T34GXH

Buffers, Drivers, Receivers, Transceivers Overview

The 74AUP1T34GXH is a single dual supply translating buffer from the Nexperia 74AUP series, housed in a 5-X2SON (SOT1226-3) package. It features Schmitt-trigger inputs and IOFF circuitry for partial power-down protection. Supply voltages VCC(A) and VCC(Y) range from 1.1 V to 3.6 V. Static current is typically 0.5 µA at 25 °C and up to 1.4 µA at +125 °C. Propagation delay ranges from approximately 2.9 ns to 33.5 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 prevents damaging backflow currents during partial power-down states

Buffers, Drivers, Receivers, Transceivers Applications

• Partial power-down applications requiring isolation of powered-down ports
• Translation between low-voltage logic domains within the 1.1 V to 3.6 V range
• Systems requiring high noise immunity with slow signal transitions

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix GXH corresponds to the X2SON5 (SOT1226-3) package variant. Confirm that the ordering code matches the required temperature range of -40 °C to +125 °C. Ensure compatibility with the manufacturer's RoHS3 compliance standards before finalizing procurement orders.

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 designs. Verify that the application does not exceed the maximum output current ratings or require higher voltage tolerances than specified.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the IOFF feature function?

The IOFF circuitry disables the output when the device is powered down, preventing potentially damaging backflow current through the device.

What is the input voltage tolerance?

The inputs are overvoltage tolerant to 3.6 V, allowing them to interface with systems operating at higher voltages while the device itself operates at lower supplies.
