Drivers, Receivers, Transceivers FAQ

What is the maximum fault voltage the LTC2864 can withstand?

The device provides ±60V fault protection on the A, B, Y, and Z pins during all modes of operation, including power-down.

Does the LTC2864 support failsafe operation?

Yes, it guarantees failsafe receiver operation when inputs are shorted, left open, or terminated but not driven, ensuring a logic 1 state at the output.

What is the ESD protection rating for the interface pins?

The interface pins (A, B, Y, Z) feature ±15kV HBM ESD protection without latchup or damage.
