DM74145

Full decoding of input logic
80 mA sink-current capability
All outputs are OFF for invalid BCD input conditions

  These DM74145 BCD-to-decimal decoders/drivers consist of eight inverters and ten, four-input NAND gates. The invertersof DM74145  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 (1015) binary input conditions. These DM74145 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.
