NOTES ON CORRECT USE
(1) Observe precautions for handling because of electro-static sensitive devices.
(2) Form a ground pattern as widely as possible to minimize ground impedance (to prevent undesired oscillation).
All the ground terminals must be connected together with wide ground pattern to decrease impedance difference.
(3) The bypass capacitor should be attached to the VCC line.
(4) The DC cut capacitor should be attached to Input and Output pin.
(5) Pin 1 (NC) should be connected to the ground pattern.
