Hi,

I am thinking to use AM26LV31 /32 in multi-drop communication up to 20 devices over 2 meter distance.

Is it possible to use AM26LV31/32 in multi-drop configuration? : One AM26LS31 with mutlple AM26LS32.

Hi,

You can refer to this app note about the unit load and maximum number of nodes, which is governed by the receiver's input impedance (7kOhm for AM26LV32 and 12kOhm for AM26LS32 => 20 max node for AM26LV32 and 32 max node for AM26LS32). The drivers can be used interchangeably.

Regards,

Hao
