Electrical characteristics

5.5 V < VS < 28 V, -40 °C < Tj < 150 °C, unless otherwise specified.

The device is still operative and functional at higher temperatures (up to 175°C).

Note:

Parameter limits at temperatures higher than 150°C may change respect to what is

specified as per the standard temperature range.



Device functionality at high temperature is guaranteed by characterization.
