The 74VCX16245 is an advanced performance, non-inverting 16-bit transceiver. It is designed for very high-speed, very low-power operation in 1.8V, 2.5V or 3.3V systems.

When operating at 2.5V (or 1.8V) the part is designed to tolerate voltages it may encounter on either inputs or outputs when interfacing to 3.3V busses. It is guaranteed to be over-voltage tolerant to 3.6V.

The VCX16245 is designed with byte control. It can be operated as two separate octals, or with the controls tied together, as a 16-bit wide function. The Transmit/Receive (T/Rbarn) inputs determine the direction of data flow through the bi-directional transceiver. Transmit (active-HIGH) enables data from A ports to B ports; Receive (active-LOW) enables data from B to A ports. The Output Enable inputs (OEn)bar, when HIGH, disable both A and B ports by placing them in a HIGH Z condition.
