Abstract
An IC for an active terminator has not only a plurality of pairs each corresponding to a different line of a bus and including a terminal resistor and a buffer amplifier which serves to output a specified voltage through the corresponding terminal resistor to the corresponding bus line, but also a similar pair of an additional buffer amplifier and an additional resistor. One end of the additional resistor is connected to the additional buffer amplifier and the other end of the additional resistor is connected to a pair of pads. Each of these terminal resistors may be connected to adjustment resistors each connected to its own additional buffer amplifier serving to output a specified voltage through the corresponding adjustment resistor to the corresponding line. These additional buffer amplifiers are controlled by a control signal received through their individual control lines which are grouped, the lines in each group being connected together into a common line which contains a repair part where it can be cut.
