Drivers, Receivers, Transceivers FAQ

What is the purpose of the CD pin?

The CD pin is an open-drain active low carrier detect output that indicates the presence or absence of a signal on the bus.

How does the receiver fail-safe work?

The receiver forces the output high when inputs are floating, shorted, or terminated without a signal, ensuring a known state.

What is the ESD rating of the A and B pins?

The A and B pins withstand -15kV using the Human Body Model and meet IEC-1000-4-2 Level 4 contact and Level 3 air discharge ratings.
