The LVCR2245A octal bus transceiver is built using advanced dual metal CMOS technology. This device 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 device so the buses are effectively isolated. The LVCR2245A has series resistors in the output structure which will significantly reduce line noise when used with light loads. The driver has been designed to drive 12mA at the designated threshold. Inputs can be driven from either 3.3V or 5V devices. This feature allows the use of this device as a translator in a mixed 3.3V/5V environment.
