This device has a two-input active-low AND enable gate controlling all eight data buffers.
Octal buffers truth table:
6.4.13374xx47 (BCD-to-seven segment dec)
The 7447 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.
