Notes:
*
9. Add a capacitor to the logic block power supply line so that the logic block power supply voltage V
DD
rise time when power is applied and the logic
block power supply voltage V
DD
fall time when power drops are both at least 1 ms, as the LC75804E/W is reset by the VDET.
*
10. If the RES pin is not used for system reset, it must be connected to the logic block power supply V
DD
.
*
11. The DO pin, being an open-drain output, requires a pull-up resistor. Select a resistance (between 1 to 10 k
) appropriate for the capacitance of
the external wiring so that signal waveforms are not degraded.
