Electrical specification

2.1

Absolute maximum ratings

Note:

Max. ESD voltages are ±2kV with human body model C = 100pF, R = 1.5k corresponds to

maximum energy dissipation 0.2mJ according to MIL883C.

Electrical characteristics

The electrical characteristics are valid within the below defined operating conditions, unless

otherwise specified. The function is guaranteed by design until TJSDon temperature

shutdown switch-on-threshold.
