7.6 tON(EN) and tOFF(EN)
Turn-on time is defined as the time taken by the output of the device to rise to 10% after the enable has risen past the 50% threshold. The 10% measurement is utilized to provide the timing of the device, system level timing can then account for the time constant added from the load resistance and load capacitance. Figure 7-6 shows the setup used to measure transition time, denoted by the symbol tON(EN).
Turn-off time is defined as the time taken by the output of the device to fall to 90% after the enable has fallen past the 50% threshold. The 90% measurement is utilized to provide the timing of the device, system level timing can then account for the time constant added from the load resistance and load capacitance. Figure 7-6 shows the setup used to measure transition time, denoted by the symbol tOFF(EN).
