BCD-to-Decimal Decoders/Drivers
General Description
These BCD-to-decimal decoders/drivers consist of eight
inverters 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
(10–15) 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 com-
patible for interfacing with most MOS integrated circuits.
