PRODUCTION DATA.
In most circumstances, a 0.1-μF VCC bypass capacitor and a 1-μF VL bypass capacitor are adequate. In applications that are sensitive to power-supply noise, use larger value VCC bypass capacitor. There is no maximum limit for bypass capacitor. Place bypass capacitors as close to the IC as possible.
It is not recommended to use this device when VCC is powered and VL= 0 V or floating for an extended period of time because operation is undefined. VCC and VL must be powered to guarantee charge pump operation.
Also, to achieve full functionality as described in Specifications, it is recommended to not use a higher voltage on VL than VCC. Full functionality can be achieved when VCC is greater than or equal to VL.
