SN74AVC4T245DRE4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AVC4T245DRE4 is a 4-bit dual-supply bus transceiver with configurable voltage-level shifting and 3-state outputs. It utilizes two separate power rails, VCCA and VCCB, each accepting voltages from 1.2V to 3.6V. The device supports asynchronous communication between data buses with maximum data rates up to 380Mbps for 1.8V to 3.3V translation. Control inputs are referenced to VCCA. I/Os are 4.6V tolerant, and the Ioff feature enables partial power-down mode operation.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Fully configurable dual-rail design allows independent port operation across the full 1.2V to 3.6V supply range.
• I/O pins provide 4.6V tolerance for interfacing with higher voltage nodes.
• Ioff circuitry disables outputs during partial power-down to prevent damaging current backflow.
• Control input logic levels are referenced directly to the VCCA supply voltage.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package type associated with the RE4 suffix against the manufacturer's official documentation before procurement. Confirm that the component meets all required environmental and electrical specifications for the intended application environment. Ensure compatibility with existing board layouts and signal integrity requirements.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when bidirectional level translation is required between different low-voltage logic families. The dual-supply architecture accommodates varying voltage nodes such as 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V. Consider the Ioff capability if the system requires safe disconnection during power cycles or standby modes.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74AVC4T245 family of 4-bit bus transceivers manufactured by Texas Instruments. The family offers various package options including SOIC, TSSOP, WQFN, and UQFN configurations. The device is designed for high-speed applications requiring reliable voltage translation between asynchronous data buses.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for SN74AVC4T245 variants with different suffixes (e.g., D, PW, RGY) which may share identical electrical characteristics but differ in physical package dimensions. Verify pinout compatibility and thermal performance metrics when substituting packages within the same functional family.
