ABSTRACT:
Information is supplied to a bus in a wired logic function, the potential on the bus either being pulled down to ground level or remaining at supply level. The data line in a bus is split into two parts which are interconnected via the main current channel a transistor. Different supply voltages are used on the two parts. The control electrode of the transistor is connected to the lowest of the supply voltages. The transistor becomes conductive when either of the parts is pulled down. The transistor is non-conductive when none of the parts is pulled down.
