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 VI 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.
