Drivers, Receivers, Transceivers FAQ

What is the maximum data rate supported by the LTC2862IDD-1?

The LTC2862IDD-1 supports a maximum data rate of 20Mbps.

Does the device provide protection against ground loop voltages?

Yes, it features an extended common mode range of ±25V and ±60V fault protection on the A and B pins.

How does the failsafe feature operate?

It guarantees the receiver output will be in a logic 1 state when inputs are shorted, left open, or terminated but not driven, using fully balanced thresholds to minimize duty cycle distortion.
