Thermal Characteristics

3.

Specifications guaranteed by design & characterization.

4.

Specifications measured as an instantaneous quantity NOT as a time-averaged quantity.

5.

STBY is designed to be driven by an open-collector device. The input is internally pulled up with a 600 k

Ω resistor.

6.

The package thermal impedance is calculated in accordance with JESD 51.
