MC74LCX245_05 Datasheet, PDF (1/8 Pages) ON Semiconductor – Low-Voltage CMOS Octal Transceiver With 5 V−Tolerant Inputs and Outputs (3−State, Inverting)

MC74LCX245
Low−Voltage CMOS Octal
Transceiver
With 5 V−Tolerant Inputs and Outputs
(3−State, Inverting)
The MC74LCX245 is a high performance, non−inverting 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 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.
