4“S” grade T MIN–T MAX are tested with automatic test equipment at T A = –55°C and T A = +125°C.
All min and max specifications are guaranteed. Specifications shown in boldface are tested on all production units at final electrical test. Results from these tests are
used to calculate outgoing quality levels.
Specifications subject to change without notice.
