description/ordering information
These decimal decoders consist of eight inverters and ten 4-input NAND gates. The inverters are connected
in pairs to make BCD input data available for decoding by the NAND gates. Full decoding of valid input logic
ensures that all inputs remain off for all invalid input conditions.
