(1) Component qualification in accordance with JEDEC and
industry standards to ensure reliable operation over an
extended temperature range. This includes, but is not limited
to, Highly Accelerated Stress Test (HAST) or biased 85/85,
temperature cycle, autoclave or unbiased HAST,
electromigration, bond intermetallic life, and mold-compound
life. Such qualification testing should not be viewed as
justifying use of this component beyond specified
performance and environmental limits.
This device consist of two independent voltage comparators that are designed to operate from a single power
supply over a wide range of voltages. Operation from dual supplies also is possible as long as the difference
between the two supplies is 2 V to 36 V, and V
CC
is at least 1.5 V more positive than the input common-mode
voltage. Current drain is independent of the supply voltage. The outputs can be connected to other
open-collector outputs to achieve wired-AND relationships.
The LM293-EP is characterized for operation from – 55 ° C to 125 ° C.
