MC74LCX245

Low-Voltage CMOS Octal

Transceiver

With 5 V−Tolerant Inputs and Outputs

(3−State, Non−Inverting)

transceiver operating from a 2.0 to 5.5 V supply. High impedance TTL

compatible inputs significantly reduce current loading to input drivers

while TTL compatible outputs offer improved switching noise

performance. A V

to be safely driven from 5 V devices if V

MC74LCX245 is suitable for memory address driving and all TTL

level bus oriented transceiver applications.

Transmit/Receive (T/R) input determines 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 input, when HIGH,

disables both A and B ports by placing them in a HIGH Z condition.
