7.6 Switching Characteristics

Refer to the timing test circuit in Figure 8-1 (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 VIN is already in steady state condition before the ON pin is asserted high.
