MC74LCX245/D
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 V
I
specification of 5.5 V allows MC74LCX245 inputs
to be safely driven from 5 V devices if V
CC
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.
