A - Turn-off delay in Dual Delay and Delayed Release mode.

B - Turn-on delay in Dual Delay and Delayed Operate mode; one-shot period in One-Shot mode.

C - Output remains on in Delayed Release and Dual Delay modes due to negative trigger

transition before the turn-off delay is over.

D - Output remains off in Delayed Operate mode due to positive trigger transition before

the turn-on delay is over.

E - One-Shot period extended by re-triggering.

FIGURE 4. LS7210 TIMING DIAGRAM

Note 1. - A,B and Trigger inputs are clocked into the input latches with the negative edge of the time-base clock.

Note 2. - In all modes except One-Shot, the output changes with the positive transition of the time-base clock.

In One-Shot mode the output is turned on with the negative transition and turned off with the

positive transition of the time-base clock.
