(1) Limits are 100% production tested at 25°C. Limits over the operating temperature range are ensured through correlation using Statistical
Quality Control (SQC) methods. The limits are used to calculate Average Outgoing Quality Level (AOQL).
(2) The ON/OFF inputs must be properly driven to prevent misoperation. For details, see Operation With ON/OFF Control.
