This parameter is guaranteed by design but need not be tested. Typical parameters are representative of actual device performance but are for reference only.

Industrial grade and 'E' suffix devices shall be tested to subgroup 1 unless otherwise specified.

Military grade devices ('H' suffix) shall be 100% tested to subgroups 1,2 and 3.

Actual switching frequency can be load dependent if output current is low. Refer to typical performance curves.

Continuous operation at or above absolute maximum ratings may adversely effect the device performance and/or life cycle.
