SEMICONDUCTOR TECHNICAL DATA  
The MC74LCX244 is a high performance, non–inverting octal buffer  
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

LOW–VOLTAGE CMOS  
OCTAL BUFFER  
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.  
Current drive capability is 24mA at the outputs. The Output Enable  
(OE) input, when HIGH, disables the output by placing them in a HIGH Z  
condition.
