External component values are those shown in Figure 2, except the capacitor at CT is 6.8 µF.

Timing and output amplitudes shown are nominal, and are for the indicated input signal and component values. Actual timing and

outputs will vary with the application.

Time t1 depends on the ratio of the on–off amplitude of the signal at TAI.
