the positive polarity pin must be connected to the CP pin. Non polarity
capacitors can also be used.
An external TTL clock must be input on this pin.
When power down, outputs VSS(0V, typ).
When power down, outputs VSS(0V, typ).
Connect to VSS1 with a 1.0μF capacitor which is low ESR (Equivalent
Series Resistance) over all temperature range. When this capacitor has the
polarity, the positive polarity pin must be connected to the VSS1 pin. Non
polarity capacitors can also be used.
