For the timing of input and output signals and the slew rates, please refer to Figure 3 0n page 8. The timing diagram is based on the following test conditions: A 2 kQ resistor is connected between pin 8 and ground; a 2 kQ resistor and a l nF capacitor are used as load for the power output (pins 13 and 14) simulating identical conditions as a power MOSFET, which is usually connected to the output.
