DM7442A is a BCD to decimal decoder manufactured by Fairchild Semiconductor Corporation. It consists 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 input logic ensures that all outputs remain off for all invalid (10-15) input conditions. DM7442A features include diode-clamped inputs, also for application as 4-line-to-16-line decoders and 3-line-to-8-line decoders, all outputs are high for invalid input conditions, typical power dissipation of 140 mW and typical propagation delay of 17 ns.
