A. R₁ and R₂ resistor values are determined based upon the logic level applied to the A port or B port as follows:
R₁ and R₂ = 40 kΩ when a logic level low is applied to the A port or B port.
R₁ and R₂ = 4 kΩ when a logic level high is applied to the A port or B port.
R₁ and R₂ = 70 kΩ when the port is deselected (or in High-Z or 3-state).
B. EN controls all output buffers. When EN = low, all outputs are Hi-Z.
