(TOP VIEW)  
These monolithic 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.
