Note 1: All devices are 100% production tested at TA = +25°C. Specifications over temperature limits are guaranteed by design.
Note 2: Droop is defined as the percentage change in the DC level from the start to the end of a video line. Inferred from input
clamping current with a 0.1µF coupling capacitor.
