SN74AVC4T245PWRE4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AVC4T245PWRE4 is a 4-bit dual-supply noninverting bus transceiver with configurable voltage-level shifting and 3-state outputs. It utilizes two separate power rails, VCCA and VCCB, supporting voltages from 1.2V to 3.6V. The device facilitates asynchronous communication between data buses with a maximum data rate of 380Mbps at 1.8V to 3.3V translation. It operates within an ambient temperature range of -40°C to +85°C and features I/Os tolerant up to 4.6V.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Fully configurable dual-rail design allows independent operation of ports across the full 1.2V to 3.6V supply range
• I/O pins are 4.6V tolerant for interfacing with higher voltage systems
• Integrated Ioff circuitry supports partial power-down mode by disabling outputs to prevent backflow current
• Control input logic levels are referenced to the VCCA supply voltage
