$Features & Applications

The MC74LCX541 is a high performance, non-inverting octal buffer operating from a 2.3 to 3.6V supply. This device is similar in function to the MC74LCX244, while providing flow through architecture.

High impedance TTL compatible inputs significantly reduce current loading toinput drivers while TTL compatible outputs offer improved switching noise performance. A VI specification of 5.5V allows MC74LCX541 inputs to besafely driven from 5V devices. The MC74LCX541 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(OE1bar, OE2bar) inputs, when HIGH, disables the output by placing them in a HIGH Z condition.
