74AUP1T34FW4-7

Buffers, Drivers, Receivers, Transceivers Overview

The 74AUP1T34FW4-7 is a single-bit, dual-supply translating buffer manufactured by Diodes Incorporated. It provides uni-directional logic translation from input pin A to output pin Y across different voltage domains. The device operates with VCCA and VCCB supply voltages ranging from 0.9V to 3.6V. It features three-state outputs controlled by the IOFF function when VCCA is zero. The component utilizes an X2-DFN1010-6 package and supports operation temperatures from -40°C to +125°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Dual power supply architecture enables universal low-voltage translation between any operating voltages within the specified range.
• Three-state output functionality activates during partial power-down conditions to prevent damaging backflow currents.
• Input isolation mechanism disables input circuits when VCCA is grounded, allowing floating inputs without current flow.

Buffers, Drivers, Receivers, Transceivers Applications

• Voltage level translation between logic types operating at different voltages
• Power-down signal isolation in multi-domain systems
• Portable electronics such as cell phones, tablets, and e-readers

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify that the ordering suffix FW4 corresponds specifically to the X2-DFN1010-6 package configuration. Confirm compliance with RoHS 3 and Halogen-free requirements for environmental specifications. Ensure design parameters align with the absolute maximum ratings provided in the datasheet to maintain reliability.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring unidirectional data transfer between dissimilar voltage domains. The dual-supply capability allows independent optimization of input and output thresholds. Consider the thermal resistance characteristics of the X2-DFN1010-6 package for heat dissipation requirements in dense layouts.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74AUP1T34 series of translating buffers produced by Diodes Incorporated. The FW4 suffix identifies the specific X2-DFN1010-6 surface-mount package variant. The series is designed for low-power CMOS applications requiring robust ESD protection and high noise immunity in harsh environments.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

An automotive-compliant version is available under the separate datasheet designation 74AUP1T34Q. Verify package compatibility if substituting with other variants in the 74AUP1T34 family, such as those in SOT353 or X2-DFN1410-6 packages.
