DM5445/DM7445 BCD to Decimal Decoders/Drivers
General Description
These BCD-to-decimal decoders/drivers consistof eightin-
vertersand ten, four-input NAND gates. The invertersare
connectedin pairsto make BCD input data availablefor
decodingbythe NAND gates.Full decodingof BCD input
logic ensures thatall outputs remainoffforall invalid
(10–15) binary input conditions. These decoders feature
high-performance, NPN output transistors designedforuse indicator/relay drivers,oras open-collector logic-circuit
drivers.The high-breakdown output transistorsarecompati-
blefor interfacing with most MOS integrated circuits.
Features Full decodingof input logic80mA sink-current capabilityAll outputsareofffor invalid BCD input conditions
