NOTE 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 abnormal oscillation).

(3) Keep the track length of the ground pins as short as possible.

(4) Connect a bypass capacitor (example: 1 000 pF) to the VCC pin.

(5) Frequency signal input/output pins must be each coupled with external capacitor for DC cut.
