SEMICONDUCTOR TECHNICAL DATA
VCX
LOW–VOLTAGE 1.65/2.5/3.3V
16–BIT TRANSCEIVER
The MC74VCX162245 is an advanced performance, non–inverting
16–bit transceiver. It is designed for very high–speed, very low–power
operation in 1.65V, 2.5V or 3.3V systems.
When operating at 2.5V (or 1.65V) 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 VCX162245 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. It is designed with 26 series resistors in each of the outputs to
reduce noise. 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.
