6.6 Switching Characteristics

See timing test circuit in Figure 21 (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. Test Conditions: VON = 5 V, TA = 25°C.
