MC74LCX240/D
MC74LCX240
Low-Voltage CMOS
Octal Buffer
With 5 V−Tolerant Inputs and Outputs
(3−State, Inverting)
The MC74LCX240 is a high performance, 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 MC74LCX240 inputs to be safely driven
from 5 V devices. The MC74LCX240 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 outputs by placing them in
a HIGH Z condition.
