Absolute Maximum Ratings*
Operating Range
The operating range defines the limits where function is guaranteed.
Electrical limits of applied signals are given in the operating conditions section.
Operating
Precautions
Shorting the video outputs to any other pin, even temporarily, can permanently damage
the on-chip output amplifier.
