Note 1. Absolute maximum ratings indicate limits which, when exceeded, may result in damage to the component. Electrical specifications do not apply

when operating the device outside its rated operating conditions.

Note 2. VSH must not be shorted to VSS or V+, even instantaneously, or device damage may result.

Electrical Characteristics ILC6660IK

Unless otherwise specified, all limits are at TA = 25°C; V+ = 5V, C1 = C2 = 100µF, test circuit of Figure 1, FC = open.

Boldface limits apply over the operating temperature range. (Note 3)
