Note : *1). Add a capacitor to the power supply line so that the power supply voltage VDD rise time when power is

applied and the power supply voltage VDD fall time when power drops are both at least 1 ms, as the

HL14104 is reset by the SVD.

*2). The SO pin, being an open-drain output, requires a pull-up resistor, Select a resistance (between 1 to 10kΩ)

appropriate for the capacitance of the external wiring so that signal waveforms are not degraded.
