ABSTRACT:
A data transmission circuit that converts parallel data signals into a serial data signal to transmit the serial data signal includes a clock generation circuit, an output circuit, and a shift register circuit for securely conducting data communication among internal elements regardless of the improvement in data transfer rate, the increase in manufacturing variance, the variation in power supply voltage and temperature, and the like. The clock generation circuit generates a clock signal. The output circuit is provided to output the serial data signal. The shift register circuit acquires the parallel data signals and sequentially transfers the acquired parallel data signals to the output circuit in a bitwise manner with the use of a shift operation synchronized with the clock signal from the clock generation circuit.
