A data bus transmission line termination circuit for connection either to the terminal end of a data bus or to an intermediate portion of the bus. The circuit is programmable to either a low-impedance state for connection to the terminal end of the data bus so as to provide an optimum terminating load for the bus, or to a high-impedance state for connection to an intermediate portion of the data bus so as not to load down the latter when so connected. The termination circuit is preferably formed on the same integrated circuit chip as the receiver circuit so as to be located adjacent the effective end of the total transmission line including the portion extending from the data bus proper through the connections and conductors of the board, card, module and chip to the receiver circuit on the chip.
