Low-Voltage CMOS Octal
Transceiver
With 5V-Tolerant Inputs and Outputs
(3-State, Non-Inverting)
The MC74LCX245 is a high performance, non–inverting octal
transceiver operating from a 2.7 to 3.6V 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 MC74LCX245 inputs to be
safely driven from 5V devices. The MC74LCX245 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/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.
