Abstract:
1. A low voltage, differential signal circuit, comprising: A. a first low voltage differential signal lead; B. a second low voltage differential signal lead; C. a first comparator having a non-inverting input connected to the first low voltage differential signal lead, an inverting input connected to the second low voltage differential signal lead, and an output, the first comparator requiring a voltage on the non-inverting input to be greater than a certain offset from a voltage on the inverting input before producing a logic high on the output; D. a second comparator having a non-inverting input connected to the second low voltage differential signal lead, an inverting input connected to the first low voltage differential signal lead, and an output, the second comparator requiring a voltage on the non-inverting input to be greater than a certain offset from a voltage on the inverting input before producing a logic high on the output; and E. a multiplexer having a first control input connected to the output of the first comparator and a second control input connected to the output of the second comparator.
