DM5445 DM7445 BCD to Decimal Decoders Drivers
June 1989
DM5445 DM7445 BCD to Decimal Decoders Drivers
General Description
These BCD-to-decimal decoders drivers consist of eight in-
verters and ten four-input NAND gates The inverters are
connected in pairs to make BCD input data available for
decoding by the NAND gates Full decoding of BCD input
logic ensures that all outputs remain off for all invalid
(10鈥?5) binary input conditions These decoders feature
high-performance NPN output transistors designed for use
as indicator relay drivers or as open-collector logic-circuit
drivers The high-breakdown output transistors are compati-
ble for interfacing with most MOS integrated circuits
