The MC74LCX240 is a high performance, inverting octal buffer
operating from a 2.7 to 3.6V supply. High impedance TTL compatible
inputs significantly reduce current loading to input drivers while TTL
compatible outputs offer improved switching noise performance. A VI
specification of 5.5V allows MC74LCX240 inputs to be safely driven from
5V devices. The MC74LCX240 is suitable for memory address driving
and all TTL level bus oriented transceiver applications.
Current drive capability is 24mA at the outputs. The Output Enable
(OE) input, when HIGH, disables the outputs by placing them in a HIGH Z
condition.
