In accordance with one or more embodiments, an apparatus includes a multi-pin connector having signal-carrying electrodes that communicate with a device external to the apparatus, and respective field-effect switches that couple the signal-carrying electrodes to respective communication channels in the apparatus.

A bias circuit mitigates cross-talk between the communication channels by biasing the channel region of the first field-effect semiconductor switch (in an off state) to boost the threshold switching voltage over a threshold discharge voltage of the ESD circuit.
