(1) Datasheet min/max specification limits are specified by design, test, or statistical analysis. The ensured specifications apply only for the
test conditions listed. Some performance characteristics may change when the device is not operated under the listed test conditions.
(2) Typical values represent the most likely parametric norm as determined at the time of characterization. Actual typical values may vary
over time and will also depend on the application and configuration. The typical values are not tested and are not ensured on shipped
production material.
(3) The supply current specified is the quiescent current for V_CC and 5V with R_L = ∞. Load resistors are not required and are not used in the
test circuit; therefore, all the supply current is used by the device.
(4) Linearity Error is the maximum variation in step height of a 16 step staircase input signal waveform with a 0.7 V_PP level at the input. All
16 are steps equal, with each at least 100 ns in duration.
(5) Input from RGB signal generator: t_r, t_f = 1.5 ns. Input from SDTV YP_BP_R signal generator: t_r, t_f = 15 ns. Input from HDTV YP_BP_R signal
generator: t_r, t_f = 8 ns.
