DM74145 BCD to Decimal Decoders/Drivers September 1986 Revised February 2000 DM74145 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 compatible for interfacing with most MOS integrat...
