7.1 Overview

The SN74LVCC3245A device is designed for asynchronous communication between data buses. Glitch-free power supply sequencing allows either supply rail to be powered on or off in any order while providing robust power sequencing performance. The device transmits data from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the direction-control (DIR) input. The output-enable (OE) input can be used to disable the device so the buses are effectively isolated. The control circuitry (DIR, OE) is powered by VCCA.
