the High-Impedance State

This 32-bit noninverting bus transceiver uses two separate configurable power-supply rails. The A port is

translation between any of the 1.5-V, 1.8-V, 2.5-V, and 3.3-V voltage nodes.

The SN74AVCB324245 is designed for asynchronous communication between data buses. 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 outputs so the buses are

effectively isolated.

resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.

both ports are in the high-impedance state.
