Abstract
An integrated circuit isolator for providing data transfer of digital data signals across a voltage isolation barrier includes an integrated circuit package having a first plurality of input data pins on one side of the isolation barrier and a corresponding plurality of output data pins on the other side of the isolation boundary. First circuitry is associated with the first plurality of input data pins and second circuitry is associated with the plurality of output data pins. A communications interface provides across the voltage isolation barrier a first communications channel for communicating data from the first circuitry to the second circuitry and a second communications channel for communicating synchronization clock data from the first circuitry to the second circuitry. The first circuitry is operable to communicate information from input digital data overlapping each other in time and received on two or more of the associated first plurality of input data pins across the first communications channel and to communicate the synchronization clock signal across the second communications channel. The second circuitry is operable to receive the communicated data from the first c…
