7.2.73 4511(BCD-to-seven segment latch/Dec)
The 4511 BCD (Binary-Coded Decimal)-to-seven-segment latch 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.
