Abstract
An apparatus for coupling digital data from a data generator to a readout device and providing electrical isolation therebetween. The apparatus including a control signal generator which couples digital data, representative of the data from the data generator, to a switch which responds thereto and couples data representative thereof to an isolation device. Operation of the switch is performed without external voltage supplies, all switching being accomplished entirely with the voltages coupled from the control signal generator to the switch. The isolation device converts the electrical signals to light signals that are then coupled to a light sensitive device which converts the light signals to digital electrical signals for coupling to the readout device.
