MC74LCX244/D
MC74LCX244
Low-Voltage CMOS Octal
Buffer
With 5 V−Tolerant Inputs and Outputs
(3−State, Non−Inverting)
The MC74LCX244 is a high performance, non−inverting octal
buffer operating from a 2.3 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 MC74LCX244 inputs
to be safely driven from 5 V devices. The MC74LCX244 is suitable
for memory address driving and all TTL level bus oriented transceiver
applications.
Current drive capability is 24 mA at the outputs. The Output Enable
(OE
) input, when HIGH, disables the output by placing them in
a HIGH Z condition.
