MC74LCX541
Low-Voltage CMOS Octal
Buffer Flow Through Pinout
With 5 V−Tolerant Inputs and Outputs
(3−State, Non−Inverting)
http://onsemi.com
The MC74LCX541 is a high performance, non−inverting octal
buffer operating from a 2.3 to 3.6 V supply. This device is similar in
function to the MC74LCX244, 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 specification of
I
5.5 V allows MC74LCX541 inputs to be safely driven from 5 V
devices. The MC74LCX541 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 output by placing them
in a HIGH Z condition.
