In a memory system having a data bus transferring data in either direction, highly reliable data transfer is provided regardless of the direction in which data is transferred. The signal lines of a data bus (12) bidirectionally transfer data. That is to say, during data write operations to a DIMM, the signal lines transfer data from a memory controller (10) to the DIMM, and during data read operations, they transfer data from the DIMM to the memory controller (10). The signal lines have, as term...

An output driver includes a predriver circuit coupled to a complimentary MOS transistor pair. Third and fourth complimentary MOS transistors are coupled between a source-drain pair of the first and second MOS transistors, respectively and an output. The back gate of at least one of the third and fourth transistors is coupled to the output to provide a lower V.sub.T at the beginning of a transition without creating excessive undershoot or overshoot. A diode is coupled in parallel with the source-...

A bus system has a bus constructed of a plurality of signal lines for transmission of signals, first and second terminating resistors provided at both ends of the respective signal lines, first, second and third modules coupled to the bus between the first and second terminating resistors and being each operative to transmit a signal through an output circuit of open drain type, first series resistors inserted in the respective signal lines between the first and second modules, and second series...

The invention relates to a bus driver having an inverter for driving a preferably clocked signal on a bus line. In the event of a capacitive coupling of the bus line to at least one neighboring bus line, a number of secondary inverters corresponding to the number of capacitively coupled bus lines are connected in parallel with the inverter of the bus driver. A simple logic combination supplies the necessary activating signals for the parallel connection of the secondary inverters. As a result, a...

Disclosed is a bus bridge for mutually connecting a memory bus having memories connected thereto and an I/O bus having plural I/O devices connected thereto, which comprises a conversion table in which pairs of entry and physical address are included and which is divided into a fixed part and a refillable part; an address conversion means for converting a logical address supplied from the I/O device to a physical address supplied to the memory, while selectively using the fixed part or the refill...

A bus circuit of this invention has a bus line. A bus input circuit and a bus output circuit are connected to the bus line. The bus line is charged by a precharge circuit. The bus output circuit outputs an output signal to the bus line by discharging or not discharging potential of the bus line. The bus input circuit inputs a signal from the bus line. The bus input circuit includes a feedback circuit which inputs potential of the bus line as the signal, amplifies the signal in accordance with a ...

A plug-in bus duct comprised of a group of elongated, flat busbars positioned in side-by-side relation within an elongated housing, the housing having the side walls of a height substantially greater than the width of the busbars. Insulator sheets separate the busbars one from the other, and from the sides of the housing, to form a side wall-insulator sheet-busbar `sandwich.` In preferred form, the busbars are all of the same cross-sectional configuration and dimensions, and each retains a plana...

A clamping connector is provided for connecting bus bars, which includes a pressure plate having a planar contact with the bus bars and a domed pressure piece which is formed so as to connect bus bars of different cross sections. The clamp bolt or bolts are disposed within flanges of the pressure plate, which are arranged between the bus bars to be connected and which the bus bars engage on both sides.

A bus bar having a T-shaped cross section for receiving a sliding bus connector which is provided with a T-shaped recess corresponding to the T-shaped bus bar is disclosed herein. The bus connector is further provided with an aperture which is in partial communication with said recess to receive a suitable cable conductor therein. A set screw assures intimate contact of the wire conductor and the bus bar because of the common communication and the set screw pressure on the cable simultaneously f...

The invention relates to a modular building construction such as a bus shelter or the like in which each pair of adjacent spaced uprights carry an H-shaped extrusion providing an elongated upper channel in which an inwardly directed generally horizontal back flange of a molded plastic roof section rests. An elongated extruded retainer element is secured to the cross piece of the H so as to clamp the flange between the cross piece and the retainer with an upwardly and rearwardly extending portion...
