SN74AVC4T245PWR-P

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AVC4T245PWR is a 4-bit dual-supply noninverting bus transceiver in a 16-pin TSSOP package. It supports configurable voltage translation between A and B ports operating from 1.2V to 3.6V. Maximum data rates reach 380Mbps for 1.8V to 3.3V translation, with propagation delays as low as 2.9ns at 3.3V. The device features 3-state outputs, I/Os tolerant up to 4.6V, and partial power-down support via the Ioff circuit.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Fully configurable dual-rail design allows independent operation of each port across the full 1.2V to 3.6V supply range.
• Ioff circuitry disables outputs to prevent damaging current backflow during partial power-down mode.
• Direction control inputs reference VCCA voltage levels to manage bidirectional data flow between buses.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the device handle partial power-down?

The Ioff circuit disables the output circuits when the device is powered down, preventing backflow current through the device.

What determines the direction of data transmission?

The logic level of the DIR input determines the direction; a high level enables transmission from A to B, while a low level enables transmission from B to A.
