(when gnd > pinb and gnd > pina, the p-n junction operates as a parasitic diode.) parasiti c diodes can occur inevitably in the structure of the ic. the operation of parasitic diodes can result in mutual interferenc e among circuits as well as operation faults and physical damage. accordingly, you must not use methods by which parasitic diodes operat e, such as applying a voltage that is lower than the gnd(p substrate)voltage to an input pin. 9. common impedance power supply and ground wiring should reflect consideration of the need to lower common impedance and minimize ripple as much as possible (by making wiring as short and thick as possible or rejecting ripple by incorporating inductance and capacitance). 10. pin short and mistake fitting do not short-circuit between out pin and vcc pin, out pin and gnd pin, or vcc pin and gnd pin. when soldering the ic on circuit board, please be unusually cautious about theor ientation and the position of the ic. fig.35 p substrate parasitic diode gnd n p n p p resistance parasitic diode n p n n p p transistor (npn) b n e gnd p substrate gnd b c e other adjacent components parasitic diode gnd parasitic diode (pinb) (pina) (pinb) (pina) fig.34 simplified structure of a bipolar ic
