NOTES:
5. V_CM = ±2.5V. At -40^oC Product is tested at V_CM = ±2.25V because Short Test Duration does not allow self heating.
6. V_OUT switches from -2V to +2V, or from +2V to -2V. Specification is from the 25% to 75% points.
7. FPBW = ₂-^S---_π-^l--^e-_V--^w--_P----^R-_E----^aA---^t--^eK-- ; VPEAK = 2V .
8. R_L = 100Ω, V_OUT = 1V. Measured from 10% to 90% points for rise/fall times; from 50% points of input and output for propagation delay.
9. A. Production Tested; B. Typical or Guaranteed Limit based on characterization; C. Design Typical for information only.
10. Measured with a VM700A video tester using an NTC-7 composite VITS.
11. V_OUT = ±2.5V. At -40^oC Product is tested at V_OUT = ±2.25V because Short Test Duration does not allow self heating.
