5442A�DM5442A�DM7442A BCD to Decimal Decoders is a logic circuit device produced by National Semiconductor.
This document provides technical specifications and electrical characteristics for the 5442A/DM5442A/DM7442A family of BCD-to-decimal decoders. The devices consist of eight inverters and ten four-input NAND gates, ensuring all outputs remain off for invalid input conditions (10-15). They are also suitable for application as 4-line-to-16-line or 3-line-to-8-line decoders.
