DM54LS42 BCD/Decimal Decoders

DM54LS42 BCD/Decimal Decoders

These BCD-to-decimal decoders 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 input logic ensures that all outputs remain off for all invalid (10–15) input conditions Connec.
