The MC74LCX240 is a high performance, inverting octal buffer operating from a 2.7 to 3.6V supply. High impedance TTL compatible inputsMC145572FNR2 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 devicesMC145572FNR2.The MC74LCX240 is suitable for memory address driving and all TTL level bus oriented transceiver applications.
Current drive capability is 24mA at the outputsMC145572FNR2. The Output Enable (OE) input, when HIGH, disables the outputs by placing them in a HIGH Z condition.
