NOTE3:

NOTE4:

NOTE5:

The series resistor R5 at PSONB can not be omitted.（R5 = 300Ω is suggested）

The series resistor R4 = 100Ω and diode D1 at PGO is suggested. If not, should add on

testing-board or burning-board at least.

Supply and signal must pass through the capacitor first before into IC.

The capacitor 0.1uF & 22uF at VCC is suggested. And diode D2 & D3 at VCC can not be

omitted

When VCC use single power, diode D2 at VCC can not be omitted.
