Low-Voltage CMOS Octal
Buffer
With 5V-Tolerant Inputs and Outputs
(3-State, Non-Inverting)
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 V I
specification of 5.5V allows MC74LCX244 inputs to be safely driven from
5V devices. The MC74LCX244 is suitable for memory address driving
and all TTL level bus oriented transceiver applications.
(OE) input, when HIGH, disables the output by placing them in a HIGH Z
condition.
