NOTES: A. C
L
includes probe and jig capacitance.
B. Input rise and fall times are 3 ns, 150 ns < pulse duration < 10 µs for both low-to-high and high-to-low transitions.
Slew rate is measured between 0.4 V and 0.9 V for the rising edge and between 2.4 V and 1.9 V for the falling edge.
C. Input rise and fall times are 3 ns. Rise and fall times (open drain) < 120 ns.
D. The outputs are measured one at a time, with one transition per measurement.
