Приемопередатчик, неинвертирующий24 мА, 24 мА2 В ~ 5,5 В

Overview

The MC74LCX245DT is a high performance, non-inverting octal transceiver operating from a 2.0 to 5.5V 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 5.5V allows MC74LCX245DT inputs to be safely driven from 5V devices. The MC74LCX245DT is suitable for memory address driving and all TTL level bus oriented transceiver applications. Current drive capability is 24mA at both A and B ports. The Transmit/Receive (T/Rbar) 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.
