6. The maximum usable resistance RX is a function of the leakage of the capacitor CX, leakage of the MC14538B, and leakage due to board
layout and surface resistance. Susceptibility to externally induced noise signals may occur for RX > 1 MW..
7. If CX > 15 mF, use discharge protection diode per Fig. 11.
