3 to 8 decoder
The 3 to 8 decoder unit takes 3 address lines as input and outputs 8 address enable lines. Which of the 8 output is enabled is dependant upon the configuration of the 3 address line. If A0, A1, and A2 are all 0, then address 0 is enabled. If A0=0, A1=1, A2=0, then address 3 is enables. With 3 address lines, the number of words that can be addressed is 8 (2^3=8).
