1. The AAT4292 is guaranteed to meet performance specification over the –40°C to +85°C operating temperature range, and is assured by design, characterization and correla-
tion with statistical process controls.
2. tD(ON) is the time after latch timeout to 90% of the output voltage.
3. tD(OFF) is the time after off timeout to 10% of the output voltage.
