Hello Team,
We are using ISO7763-Q1 isolator in our project, VCC1 and VCC2 is connected to 5V regulator.
INB is connected to a clock signal from Micro with clock frequency max 1kHz through 2K ohm resistor.
with this no issues.
Now, for the same application if we use ISO6763 instead of 7763, we measured that the clock from micro is pulled HIGH for 180-190 ms constantly, aft that we can see oscillations on clock (refer image attached)
Note; No other components or test conditions varied except change of isolator. In image attached , Pink is CLK and Yellow is reference point.
Why ??
