Other Parts Discussed in Thread: SN74LV8151
Hi Expert
We found that when we use B side as input A side as output ,the output have ringing.
This is sch.
The input is conected optocoupler , After the photocoupling state changes, a series of jitter is found after the output level is switched. Below red is input ,yellow is output .
Below yellow is input(TP79) ,red is output(TP78) .
Below YELLOW is input , red is output .
We test found ；
1. In many times test ,the jitter is occur in input lever 5V .
2. We use signal generator as input ,Adjusting the time of rising edge, it is found that the output signal no longer jitter when rising to a certain extent.
3. According to datasheet all used IO push pull , the jetter is still exsit.
4.We use A side as input ,B side as output ,the jetter not occur .
