MC74LCX540

Low-Voltage CMOS

Octal Buffer

Flow Through Pinout

With 5 V−Tolerant Inputs and Outputs

(3−State, Inverting)

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 V

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.

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

in a HIGH Z condition.
