Abstract

PURPOSE:To fix an arbitrary signal line of a logical circuit to a specified logical level, by providing a tie-up means fixing the potential of a signal line of the logical circuit to a specified logical level, with a termination resistor chip integrating the termination resistor of the signal line. CONSTITUTION:Signal lines 51, 52 connecting logical circuit chips 1, 2 are connected to a termination resistor chip 7 around the termination of the signal lines. The chip 7 is provided with tie-up switches 91, 92...9n, each switch can be a mechanical switch, one end is connected to leads 61, 62...6n, another end is connected to a common power supply and has equal logical level for the logical circuit chips 1, 2 gate circuits 31, 32, 41, 42 and the like. The potential of the signal line 51 can be tied up to a Vc compulsively by turning on a tie-up switch 91 connected to the desired signal line, e.g., 51, and the logical level of the signal line 51 can be fixed to the desired logical level corresponding to the power supply Vc.
