With 3.6V–Tolerant Inputs and Outputs
(3–State, Non–Inverting)
The NL74VCX16245 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.
