Notes:
1. A capacitor must be added to the power line so that both the power supply voltage (VDD) rise time when power is applied and the power supply
voltage (VDD) fall time when power drops are at least 1 ms.
2. DO is an open – drain output and requires a pull-high resistor between 1KΩ to 10KΩ. The pull-up resistor value must be appropriate to the capacitor
of the external wiring so that the signal wave forms are not degraded.
