描述 Description

The ET74LCX244 is a high performance, non-inverting octal buffer operating from a 2.3 to 5.5V 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 ET74LCX244 inputs to be safely driven from 5V devices. The ET74LCX244 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, disable the output by placing them in a HIGH Z condition.
