Abstract:
A serial/parallel converter, comprising:a plurality of serial input/output switching latches that both receive and output a serial data signal;a plurality of parallel input/output switching latches that both receive and output a parallel data signal;a first logic circuit that logically processes a control signal and a selection signal;a second logic circuit that logically processes an output signal of the first logic circuit;a first plurality of transmission gates controlled by output signals from the first and second logic circuits, wherein each of the first transmission gates respectively transmits both an output signal and an input signal between a first terminal of each of the parallel input/output switching latches and a second terminal of a corresponding one of the serial input/output switching latches; andsecond and third pluralities of transmission gates that transmit both the input signal and the output signal between the second terminal of one serial input/output switching latch and a first terminal of a corresponding serial input/output switching latch, wherein the second plurality of transmission gates is controlled by the output signals of the first and second logic circuits, and wherein the third plurality of transmission gates is controlled by the selection signal and an inverted selection signal.
