MC74LCX245
LowVoltage CMOS Octal
Transceiver
With 5 VTolerant Inputs and Outputs
(3State, Inverting)
The MC74LCX245 is a high performance, noninverting octal
transceiver operating from a 2.3 to 3.6 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
I
specification of 5.5 V allows MC74LCX245 inputs
to be safely driven from 5 V devices. 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 bidirectional transceiver. Transmit (activeHIGH)
enables data from A ports to B ports; Receive (activeLOW) 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.
