Disclosed is a data display circuit which comprises a shift register circuit including six cascade-connected shift registers shifting serial data to produce parallel data, a decoder circuit including three decoders receiving the parallel data from the shift register circuit and producing output data corresponding to such input data, a latch circuit coupled to the decoder circuit, a control circuit coupled to the decoder circuit and the latch circuit and supplying these decoder and latch circuits with control pulses so that output data from the decoder circuit may be held temporarily in the latch circuit, and a display device for displaying output data from the latch circuit. In this data display circuit, the three decoders have input terminals coupled respectively with the output terminals of different groups of four cascade-connected shift registers of the shift register circuit, and the control circuit energizes the three decoders at different times, thereby applying substantially the same data from the shift registers to the decoders.
A data display circuit comprising a decoding means including a plurality of decoders which receive parallel data with predetermined delay time and decode the individual input parallel data, a plurality of common lines connecting in common the corresponding output terminals of said plurality of decoders, latch means including a plurality of latches with input terminals severally coupled to said common lines, control means for supplying said plurality of decoders with respective control signals with said predetermined delay time and transferring the output data from said individual decoders to said latch means through said common lines, and display means for displaying the stored contents of said latch means.
