The device has two independent decoders, Multifunction capability each accepting two inputs and providing four mutually- Two completely independent 1-of-4 decoders exclusive active-LOW outputs. Each decoder has an Active LOW mutually exclusive outputs active-LOW Enable input which can be used as a data input for a 4-output demultiplexer. Each half of the AC/Outputs source/sink 24 mA ACT139 can be used as a function generator providing all ACT139 has TTL-compatible inputs four minterms of two variables.
