SN74AVC4T245PWR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AVC4T245PWR is a 4-bit dual-supply bus transceiver with configurable voltage-level shifting and 3-state outputs. It operates within a supply voltage range of 1.2V to 3.6V on both VCCA and VCCB rails. The device supports maximum data rates up to 380Mbps for 1.8V to 3.3V translation. Control inputs are referenced to VCCA, while I/Os are 4.6V tolerant. It features Ioff support for partial power-down mode and latch-up performance exceeding 100mA per JESD 78, Class II.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Configurable dual-rail design allows independent operation of ports across the full 1.2V to 3.6V power-supply range.
• Ioff circuitry disables outputs to prevent damaging current backflow during partial power-down or high-impedance states.
• Direction control and output enable inputs utilize logic levels referenced to the VCCA supply voltage.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package suffix 'PW' corresponds to the required TSSOP-16 form factor. Confirm that the ordering suffix does not alter electrical characteristics unless explicitly documented by Texas Instruments. Ensure compatibility with the target PCB footprint and thermal requirements for the selected package variant.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing asynchronous buses requiring bidirectional translation between low-voltage nodes such as 1.2V, 1.8V, 2.5V, and 3.3V. The device is suitable for applications demanding high-speed data transfer up to 380Mbps. Consider the 4.6V tolerance of I/Os for robustness against overvoltage conditions on connected lines.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74AVC4T245 family of 4-bit dual-supply bus transceivers. The 'PWR' designation indicates a tape-and-reel packaging configuration in the TSSOP-16 package. Other variants in the family include SOIC, TVSOP, WQFN, and UQFN packages, offering flexibility for different board space and thermal constraints.
