ABSTRACT:
A circut arrangement for serial data transfer has a transmitting device with several bit-parallel input information units, a serial data transfer line and a receiving device via which the transferred data are correspondingly converted into bit-parallel output information units to drive control elements or logic circuits. The data to be transferred forms on the data transfer line a data word composed of a start pulse, several information units corresponding to the number of bit-parallel input information units forming a data block, and a defined data pause. By cascading several transmitting and receiving devices of the same kind, the number of bit-parallel, input and output information units can be altered, whereby the data word on the data transfer line is also altered by sequential joining of a corresponding number of data blocks, each having the same number of information units.
