DM54145/DM74145
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 (IO-
15) binary input txrndtions. These decoders feature high-
performance, NPN output transistors designed tor use as
indicator/relay drivers, or as open-collector logio-circuit driv-
ers. The high-breakdown output transistors are compatible
for interfacing with most MOS integrated circuits.
Features
tt Full decoding of input logic
I: 80 mA sink-current capability
I: All outputs are off for invalid BCD input conditions
