About this manual

The DM54253/DM74253 is a dual, four-line multiplexer featuring full on-chip decoding to select the desired data input. It includes common select lines for both multiplexers while allowing individual control of the two outputs via separate enable lines. When the enable lines are taken to a high logic level, the outputs enter a high-impedance TRI-STATE condition.
