SN65LVDS390: SN65LVDS390PW Unused Inputs

Damian Dziedzic

Part Number: SN65LVDS390

Hello,

For the SN65LVDS390PW, what is the recommended configuration for unused LVDS inputs? Pull both inputs to VCC, GND, or leave open?

Thanks,

Damian

Please see section 10.3.2, SN65LVDS390 has an open-circuit fail-safe on its LVDS RX, so you can leave the RX input open. When this happens, the output is forced to a high-level, regardless of the differential input voltage.

Thanks

Hi Damian,

The input pins here are fail safe so they can be left open if unused.
