6.4.12974xx45 (BCD-to-Decimal Dec)
This BCD-to-decimal decoder consists of eight inverters and ten four-input NAND gates.
BCD-to-decimal truth table:
6.4.13074xx46 (BCD-to-seven segment dec)
The 7446 BCD (Binary-Coded Decimal)-to-seven-segment decoder translates a 4-bit BCD
input into hexadecimal, and outputs high on the output pins corresponding to the hexadecimal
representation of the BCD input. There are provisions for lamp testing and for blanking the
outputs.
