... MC74AC138/74ACT138 devices and one MC74AC138/74ACT138 can be used as an 8–output (O 0 – The demultiplexer by using one of the active LOW Enable inputs as the data input and the other Enable inputs as strobes. The Enable inputs which are not used must be permanently tied to their appropriate active– ...
