7 Operation at high ambient temperature requires a thermally optimized PCB layout (see the Applications section), input data update rate not exceeding 85 MHz, black-

to-white transition ≤ 4V and CL ≤ 150 pF. In systems with limited or no airflow, the maximum ambient operating temperature is limited to 75°C. For operation above

75°C, see Note 8 below.

8 In addition to the requirements stated in Note 7 above, operation at 85°C ambient temperature requires 200 lfm airflow.
