The MC74LCX240 is a high performance, 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 VI
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.
Current drive capability is 24mA at the outputs. The Output Enable
(OE) input, when HIGH, disables the outputs by placing them in a HIGH Z
condition. Designed for 2.7 to 3.6V VCC Operation 5V T olerant — Interface Capability With 5V TTL Logic Supports Live Insertion and Withdrawal IOFF Specification Guarantees High Impedance When VCC = 0V LVTTL Compatible LVCMOS Compatible 24mA Balanced Output Sink and Source Capability Near Zero Static Supply Current in All Three Logic States (10μA)
Substantially Reduces System Power Requirements Latchup Performance Exceeds 500mA ESD Performance: Human Body Model >2000V; Machine Model >200V
