The MC74LCX540 is a high performance, inverting octal buffer

operating from a 2.3 to 3.6 V supply. This device is similar in function

to the MC74LCX240, while providing flow through architecture.

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

MC74LCX540 inputs to be safely driven from 5 V devices. The

MC74LCX540 is suitable for memory address driving and all TTL

level bus oriented transceiver applications.

Current drive capability is 24 mA at the outputs. The Output Enable

(OE1, OE2) inputs, when HIGH, disables the outputs by placing them

in a HIGH Z condition.
