7.5 Transition Time

Transition time is defined as the time taken by the output of the device to rise or fall 10% after the select signal

has risen or fallen past the logic threshold. The 10% transition measurement is utilized to provide the timing of

the device. The time constant from the load resistance and load capacitance can be added to the transition time

to calculate system level timing. Figure 31 shows the setup used to measure transition time, denoted by the

symbol tTRANSITION.

7.6 tON (EN) and tOFF (EN) Time

The tON (EN) time is defined as the time taken by the output of the device to rise to 90% after the enable has fallen

past the logic threshold. The 90% measurement is used to provide the timing of the device being enabled in the

system. Figure 32 shows the setup used to measure the enable time, denoted by the symbol tON (EN).

The tOFF (EN) time is defined as the time taken by the output of the device to fall to 90% after the enable has fallen

past the logic threshold. The 90% measurement is used to provide the timing of the device being disabled in the

system. Figure 32 shows the setup used to measure enable time, denoted by the symbol tOFF (EN).
