Does this part have integrated failsafe operation? If not, is there a recommended termination scheme to facilitate failsafe externally?

Hi Ralph,

SN75976A doesn't state failsafe in the datasheet and is not provided this feature in the device.

There is a way to implement the failsafe externally. Please refer this technique in this apps notes below.

Hi Dennis,
This app note is for an LVDS receiver. The SN75976A is an RS-485 transceiver. Are you saying the app note applies to the SN75976A also?
