I'm trying to allow a user to plug and unplug a series-connected differential serial device in and out of the circuit on the fly.
When the device is plugged in the "Board Device Present" is pulled to 5V by an externally supplied 5V, at which time the switch routes the serial lines to and out of the board. When not connected, the switch is supposed to bypass the board.
This works for a few mate cycles, but after a few mating cycles, the switches no longer respond to the Board Present 5V going to the IN1/In2 lines.
Any suggestions?
