Electrical Characteristics
Limits in standard typeface are for T
less otherwise specified: V+ = 5V, C
Note 2: Absolute maximum ratings indicate limits beyond which damage to the device may occur. Electrical specifications do not apply when operating the device
beyond its rated operating conditions.
Note 3: V
temperatures above 85˚C, OUT must not be shorted to GND or V+, or device may be damaged.
Note 4: The maximum allowable power dissipation is calculated by using P
ambient temperature, and θ
Note 5: The human body model is a 100pF capacitor discharged through a 1.5kΩ resistor into each pin. The machine model is a 200pF capacitor discharged directly
into each pin.

Note 7: Specified output resistance includes internal switch resistance and capacitor ESR. See the details in the application information for positive voltage doubler.
Note 8: The output switches operate at one half of the oscillator frequency, f
