This document describes the features and characteristics of TL6517 DM5445 DM7445 BCD-to-decimal decoders-drivers. It consists of eight inverters and ten four-input NAND gates, which are used to decode BCD input data into outputs. 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 integrated circuits.
