8.9 Switching Characteristics, CT = 1000 pF
Refer to the timing test circuit in Figure 1 (unless otherwise noted) for references to external components used for the test
condition in the switching characteristics table. Switching characteristics shown below are only valid for the power-up
sequence where V_IN and V_BIAS are already in steady state condition before the EN terminal is asserted high.
