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 1k
resistor value must be appropriate to the capacitor of the external wiring so that the signal wave
forms are not degraded.
