MC74F537 Overview
MC54/74F537 1-OF-10 DECODER WITH 3-STATE OUTPUTS The MC54 / 74F537 is a one-of-ten decoder/demultiplexer with four active HIGH BCD inputs and ten mutually exclusive outputs. A polarity control input determines whether the outputs are active LOW or active HIGH. The MC54 / 74F537 has 3-state outputs, and a HIGH signal on the Output Enable (OE) input forces all outputs to the high impedance state.
