SN74AVC4T245RSVR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AVC4T245RSVR is a 4-bit noninverting bus transceiver featuring configurable voltage-level shifting and 3-state outputs. It utilizes two independent power-supply rails, VCCA and VCCB, both supporting a range of 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. It includes Ioff circuitry for partial power-down mode operation and offers ESD protection exceeding JESD 22 standards.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Fully configurable dual-rail design allows each port to operate over the full 1.2V to 3.6V power-supply range
• I/Os are 4.6V tolerant and support high-speed translation up to 380Mbps
• Ioff circuitry disables outputs to prevent damaging current backflow during partial power-down
• Control inputs VIH/VIL levels are referenced to the VCCA supply voltage

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package variant RSV (UQFN-16) matches the target PCB footprint and thermal requirements. Confirm that the control pins are powered by VCCA as specified in the datasheet. Ensure OE pin biasing follows the recommended pullup resistor guidelines to maintain high-impedance states during power transitions. Validate system compatibility with the 1.2V to 3.6V operating voltage ranges.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing systems requiring bidirectional level translation between different low-voltage nodes such as 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V. The dual-supply architecture is suitable for asynchronous communication where push-pull drivers connect to data I/Os. Consider the UQFN-16 package for space-constrained designs requiring surface-mount installation within the -40°C to +85°C temperature range.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the SN74AVC4T245 family of 4-bit dual-supply bus transceivers. The RSV suffix specifically denotes the 16-pin Ultra Small Quad Flat No-Lead (UQFN) package with dimensions of 2.6mm x 1.8mm. This packaging option provides a compact form factor suitable for portable and dense electronic applications while maintaining the electrical characteristics defined for the AVC logic series.
