Note 1: All devices are 100% tested at T
A
= +25°C. All temperature limits are guaranteed by design.
Note 2: The settling time is measured from the 50% of the input swing to the 0.1% of the final value of the output.
Note 3: Maximum load capacitance is 200pF. All the listed parameters are measured at application’s inputs, unless otherwise
noted. See the Typical Application Circuits.
Note 4: Difference in propagation delays of fast-blanking signal and RGB signals. Measured from 50% input transition to 50%
output transition. Signal levels to be determined.
Note 5: Guaranteed by design.
