SN74AVC4T245DR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AVC4T245DR is a 4-bit dual-supply noninverting bus transceiver with configurable voltage-level shifting and 3-state outputs. It utilizes separate VCCA (1.2V to 3.6V) and VCCB (1.2V to 3.6V) rails for bidirectional translation between nodes such as 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V. The device supports asynchronous communication with maximum data rates up to 380Mbps at 1.8V to 3.3V translation. Control inputs are referenced to VCCA, and the I/Os tolerate voltages up to 4.6V.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Fully configurable dual-rail design allows independent power supply selection for each port across the full 1.2V to 3.6V range.
• I/O pins feature 4.6V tolerance, enabling safe interfacing with higher voltage systems without external protection.
• Integrated Ioff circuitry disables outputs during partial power-down mode to prevent damaging current backflow.
• Direction control and output enable inputs manage data flow direction or place ports in high-impedance isolation state.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package suffix 'D' corresponds to the 16-pin SOIC format required by your PCB layout. Confirm that the operating environment remains within the specified -40°C to +85°C temperature range. Ensure input signals do not exceed the absolute maximum ratings to maintain device reliability and avoid permanent damage.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when bidirectional level translation is required between two distinct voltage domains using a single logic family. The dual-supply architecture simplifies interface design for mixed-voltage systems. Verify that the target application does not require more than four channels of simultaneous translation.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74AVC4T245 series of low-voltage bus transceivers manufactured by Texas Instruments. The 'D' suffix specifically identifies the Small Outline Integrated Circuit (SOIC) package variant. This series is designed for high-speed asynchronous communication between buses operating at different voltage levels.
