Notes:

1. Not all combinations are available – consult factory.

2. It’s not recommended to over-specify stability over temperature performance: it significantly affects the cost.

3. Unless absolutely necessary do not specify highest operating temperature above 70°C.

4. All parameters, unless otherwise specified, are at nominal conditions, i.e.: T=25°C, Nominal Vcc & Nominal Load.

5. Part number string shall contain no spaces.
