Overview

MC74LCX245 Low-Voltage CMOS Octal Transceiver With 5 V−Tolerant Inputs and Outputs (3−State, Non−Inverting) The MC74LCX245 is a high performance, non−inverting octal 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 VI specification of 5.
5 V allows MC74LCX245 inputs to be safely driven from 5 V devices if VCC is less than 5.
0 V.
The MC74LCX245 is suitable for memory address driving and all TTL level bus oriented transceiver applications.
Current drive capability is 24 mA at both A and B ports.
The 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.
