NOTES
1Temperature range (T
MIN to TMIN); 0°C to +70°C.
2Sample tested at +25
°C to ensure compliance.
3TTL input values are 0 to 3 volts, with input rise/fall times
≤3 ns, measured between the 10% and 90% points. Timing reference points at 50% for inputs and
outputs. See timing notes in Figure 1.
4This includes effects due to clock and data feedthrough as well as RGB analog crosstalk.
