VCX

LOW–VOLTAGE 1.8/2.5/3.3V

16–BIT TRANSCEIVER

The MC74VCX16245 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/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.

• Designed for Low Voltage Operation: V

• 3.6V Tolerant Inputs and Outputs

= 1.8–3.6V
