● Performing separate electrostatic damage countermeasures
When adding an externally attached electrostatic countermeasure element to the output pin, connect a varistor in the
position shown in Fig. 59 (if connected directly to the output pin, the IC could oscillate depending on the capacity of the
varistor). For this IC, since the output waveform is GND-referenced and swings positive and negative, a normal Zener
diode cannot be used.
