Low-Voltage 1.8/2.5/3.3V 16-Bit Transceiver With 3.6 V−Tolerant Inputs and Outputs (3−State, Non−Inverting)

ON Semiconductor 

74VCX16245

Low−Voltage 1.8/2.5/3.3V

16−Bit Transceiver

With 3.6 V−Tolerant Inputs and Outputs

(3−State, Non−Inverting)

The 74VCX16245 is an advanced performance, non−inverting

16−bit transceiver. It is designed for very high−speed, very low−power

operation in 1.8 V, 2.5 V or 3.3 V systems.

When operating at 2.5 V (or 1.8 V) the part is designed to tolerate

voltages it may encounter on either inputs or outputs when interfacing

to 3.3 V busses. It is guaranteed to be over−voltage tolerant to 3.6 V.

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/Rn) 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), when HIGH, disable both A and B ports by placing them

in a HIGH Z condition.
