Abstract
An electronically controllable low capacitance active bus line terminator achieves low output terminal capacitances by connecting emitters of switch transistors directly to the output terminals. Termination resistors are connected directly between an output of a voltage regulator circuit and collectors of the switch transistors. Emitters of optional clamp transistors can be connected to bases or collectors of the switch transistors to limit or prevent 'ringing' of bus conductors connected to the output terminals if the switch transistors are turned on. The bus conductors are thereby isolated from parasitic capacitances associated with the termination resistors and the collectors of the switch transistors when they are turned off.
