DM5445
DM5445 is BCD to Decimal Decoders/Drivers manufactured by National Semiconductor.
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 patible for interfacing with most MOS integrated circuits
Features
Y Full decoding of input logic Y 80 m A sink-current capability Y All outputs are off for invalid BCD input conditions
