MC74F537

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. Two input enables, active HIGH E2 and active LOW E1, are available for demultiplexing data to the selected output in either non-inverted or inverted form. Input codes greater than BCD nine cause all outputs to go to the inactive state (i.e., same polarity as the P input). 1-OF-10 DECODER WITH 3-STATE OUTPUTS FAST™ SCHOTTKY TTL Demultiplexing Capability 3-State Outputs Multiple Input Enable for Expansion Polarity Control Input ESD Protection > 4000 Volts CONNECTION DIAGRAM DIP (TOP VIEW) VCC O3 20 19 O4 18 A3 17 A2 16 E1 15 E2 14 O9 13 O8 12 O7 11 20 1 J SUFFIX CERAMIC CASE 732-03 20 1 N SUFFIX PLASTIC CASE 738-03 20 DW SUFFIX SOIC CASE 751D-03 1 1 O2 2 O1 3 O0 4 P 5 OE 6 A0 7 A1 8 O5 9 10 O6 GND ORDERING INFORMATION LOGIC DIAGRAM A3 A2 A1 A0 E1 E2 P 15 14 5 MC54FXXXJ Ceramic MC74FXXXN Plastic MC74FXXXDW SOIC LOGIC SYMBOL 4 6 7 16 17 P A0 A1 A2 A3 E1 E2 OE O0 O1 O2 O3 O4 O5 O6 O7 O8 O9 3 2 1 19 18 8 9 11 12 13 OE O0 O1 O2 O3 O4 O5 O6 O7 O8 O9 VCC = PIN 20 GND = PIN 10 Please note that this diagram is provided only for the understanding of logic operat...
