Installation Classification
1. To determine resistance and capacitance, the Si840x, SO-16, is converted into a 2-terminal device. Pins 1–8 (1-4, SO-
2. Measured from input pin to ground.
8) are shorted together to form the first terminal and pins 9–16 (5–8, SO-8) are shorted together to form the second
terminal. The parameters are then measured between these two terminals.
