    • A differential output circuit including a first output driving circuit that includes a first PMOS transistor and a first NMOS transistor connected in series to each other, a second output driving circuit that includes a second PMOS transistor and a second NMOS transistor connected in series to each other and a control circuit, wherein, when a control signal has a first value, the control circuit selectively turns on one of the first and second PMOS transistors and selectively turns on one of the first and second NMOS transistors, thereby controlling the first and second output driving circuits to output a first pair of differential signals, and when the control signal has a second value, the control circuit supplies no current to the PMOS transistors and selectively turns on one of the NMOS transistors, thereby controlling the output driving circuits to output a second pair of differential signals.
    • 一种差分输出电路,包括:第一输出驱动电路,包括彼此串联连接的第一PMOS晶体管和第一NMOS晶体管;第二输出驱动电路,包括彼此串联连接的第二PMOS晶体管和第二NMOS晶体管; 以及控制电路,其中,当控制信号具有第一值时,所述控制电路选择性地接通所述第一和第二PMOS晶体管中的一个并选择性地导通所述第一和第二NMOS晶体管中的一个,从而控制所述第一和第二输出 驱动电路输出第一对差分信号,并且当控制信号具有第二值时,控制电路不向PMOS晶体管提供电流,并选择性地导通NMOS晶体管中的一个,从而控制输出驱动电路输出 第二对差分信号。
