Abstract: PURPOSE: A current-mode bidirectional input/output buffer is provided to make a bidirectional transmission by using one transmission for transmitting data between two chips. CONSTITUTION: A current-mode bidirectional input/output buffer includes a transmitting/receiving average voltage output part(210), a reference voltage output part(220), a comparator(230), and a bias voltage generator. The transmitting/receiving average voltage output part(210) converts average current value between a transmission signal(IN1) and a transmission signal(IN2) to average voltage. The transmission signal(IN1) is transmitted to the external chip. The transmission signal(IN2) is received from external chip. The reference voltage output part(220) converts a predetermined reference current(Iref) to a reference voltage. The reference current(Iref) is selectively generated. The comparator(230) compares a voltage of the output part(210) with a voltage of the output part(220), and outputs a logic signal corresponding to a receiving signal from the external chip. The bias voltage generator generates a bias voltage to be identical with a characteristic impedance of a transmission line connected to the external chip, and provides it to each output part.
