Abstract

See full text

A circuit for carrying data between a host system and a remote unit includes first and second edge-triggered delay-type flip-flops coupled to first and second input lines, respectively. Combinational logic coupled to the output of the first flip-flop and to the first and second input lines transmits data on at least one of the input lines to the remote unit. This creates a redundancy which provides for the continued transmission of data between the host and the remote unit in the event that one of the input channels fails.
