Note: When the “soft off” function is used, a capacitor must be connected to the SOF pin. If this function is not used, this pin must be left open with absolutely

no signals or lines connected.

Notes on Wiring and Lines

Since large currents flow in the VCC and ground lines, oscillations may occur on these lines. The following points

should be observed if such oscillations occur.

(1) Lower the line impedances by making them shorter and thicker.

(2) Attach capacitors close to the IC.

(3) If the controller (CPU) is mounted on a separate printed circuit board, insert series resistors (of about 10 kΩ)

between the controller outputs and this IC.

No. 5339-3/6
