74AUP1T34GXXL

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74AUP1T34GXXL is a single dual-supply translating buffer from the 74AUP series. It features independent supply voltage ports, VCC(A) and VCC(Y), both operating within a range of 1.1 V to 3.6 V. The device provides Schmitt-trigger action for noise immunity and includes IOFF circuitry to prevent backflow current during partial power-down states. It supports an ambient temperature range of -40 °C to +125 °C and complies with JEDEC standards JESD8-7, JESD8-5, and JESD8-B.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Dual-supply architecture allowing independent voltage levels on input and output ports
• Schmitt-trigger inputs provide tolerance for slow rise and fall times
• IOFF circuitry enables safe partial power-down mode operation
• High ESD protection exceeding 5000 V (HBM) and 1000 V (CDM)

Buffers, Drivers, Receivers, Transceivers Applications

• Voltage level translation between different logic families
• Partial power-down applications requiring isolation
• Systems with varying supply voltage domains

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package suffix corresponding to 'GXXL' against official Nexperia documentation, as standard listings typically use suffixes like GW or GX. Confirm that the requested variant matches the exact pinout and thermal characteristics defined in the product data sheet before finalizing procurement specifications.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing circuits with distinct supply voltages within the 1.1 V to 3.6 V range. Ensure the design accounts for the required propagation delay variations across different load capacitances and temperature conditions specified in the dynamic characteristics tables.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the 74AUP family of low-power CMOS logic devices. It serves as a specialized translator buffer, differing from standard buffers by its ability to operate with two separate supply rails. This makes it suitable for bridging gaps between subsystems powered by different voltage levels without external components.

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 maximum input voltage rating?

The input voltage can withstand up to 4.6 V, providing overvoltage tolerance even when the device is powered down.
