Notes:
9.
All parameters specified with loaded outputs.
10. Duty cycle is measured at 1.5V when V
= 3.3V. When V
= 2.5V, duty cycle is measured at 1.25V.
11.
Determined as a fraction of 2*(Trp
–
Trn)/(Trp +Trn) Where Trp is a rising edge and Trp is an intersecting falling edge.
12. The 0.7V test load is R
= 33.2 ohm, R
= 49.9 ohm in test circuit.
13. The 1.0V test load is shown on the test circuit page.
