Hi,
For one of my design,Im planning to use the AM26LV31 and AM26LV32 device and the interface drawing is shown below.
And below is the comparison table between SP3490 and AM26LV31 and 32.

When we analysed,the 26LV31 and SP3490 transmitter output voltage seems to be different.But receiver specifications remains the same.
Could you pls advice me,whether this proposal will work without creating any problem.
Thanks-Arumugam
