I am FAE in Japanese distributor.
Our customer evaluate ADM2682E and found unnecessary “L” output.
Please see figure1, Figure2 and Figure3.
Could you tell me why RXD output unnecessary “L” ?
Best regards

This behavior is related to the dv/dt of the A/B waveform when the driver changes from output H state to high impedance (which happens on the falling edge of the DE signal)
This unnecessary L output can…
Hi Kokubo-san,
This behavior is specific to applications which have small amount of capacitance between the A and B, it is not described in the current revision of the datasheet (Rev G),
There are some…
Hi Neil san
Thank you for quick reply.
I read the following URL and understood small bus line capacitance can be low after DE=L.
