MC74VCX16245
VCX
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.
