Low-Voltage CMOS

Octal Buffer

With 5V-Tolerant Inputs and Outputs

(3-State, 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 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.

(OE) input, when HIGH, disables the outputs by placing them in a HIGH Z

condition.
