MC74LCX244_07 Datasheet, PDF (1/9 Pages) ON Semiconductor – Low−Voltage CMOS Octal Buffer With 5 V−Tolerant Inputs and Outputs (3−State, Non−Inverting)

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 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 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.
