• Design reference data
Note) The characteristics listed below are theoretical values based on the IC design and are not guaranteed.
■ Usage Notes
1. Avoid the short-circuits between output and V
CC
, and between output pin and GND.
Otherwise, the IC is likely to break down or emit smoke.
2. An appropriate prior study should be done for use of dip soldering.
