摘要： An IC which integrates an EPROM is disposed on a circuit board. Also, a pad for supplying a writing voltage to the EPROM and a voltage supplying circuit, for supplying a power voltage to power terminals of the IC, which includes a first transistor and a second transistor, are disposed on the circuit board. When the pad is supplied with a high voltage for writing the data in the EPROM, the first transistor is on, the second transistor is off, and the voltage is supplied to the EPROM as the writing voltage. When data are read from the EPROM after the circuit board is packaged, because the pad is not supplied with any voltage, the first transistor is off, the second transistor is on, and a reading voltage is supplied to the EPROM via the outer terminal.

摘要： An operational amplifier charges a charge storage capacitor in response to an input signal supplied to a non-inverting input terminal. When a switching signal is low, NPN transistors disposed in an output open circuit are on. Therefore, output transistors disposed in a push-pull circuit are off and the output signal is cut off. Further, in this situation, the potential of a phase compensation capacitor is held because AC coupling of the phase compensation capacitor does not occur.

摘要： An electronic circuit device decreases dispersion in the output of the circuit caused by changes in the resistance of the resistors resulting from stress. Resistor positions are selected on the circuit board so that a change in the circuit output caused by a change in resistance of a first resistor group becomes equal to a change caused by a change in resistance caused by a second resistor group, these changes being in opposite directions so as to cancel each other. Alternately, a plurality of resistors are connected to form a composite resistor such that the effect upon resistance of the composite resistor caused by the resistor having decreased resistance is cancelled by the effect upon resistance of the composite resistor caused by a resistor having an increased resistance.

摘要： A transmission apparatus for differential communication includes a driver bridge circuit and a pair of noise protection circuits. The driver bridge circuit includes four output devices that are independently connected between each of a pair of transmission lines and a power line or a ground line. Each noise protection circuit is provided to a corresponding transmission lines. Each noise protection circuit includes a ground potential detector and an impedance controller. The ground potential detector detects a potential of the corresponding transmission line with respect to the ground line. The impedance controller causes an impedance of the corresponding transmission line with respect to the ground line to become equal to an impedance of the other transmission line with respect to the ground line, when the detected potential becomes outside a predetermined potential range.

摘要： When a transmission signal is detected as having been changed from a high level to a low level, two transmission lines are connected for only a predetermined time through a diode by a first transistor and a second transistor. The diode is arranged such that its forward direction is from a high-side transmission line to a low-side transmission line. The diode turns on, when a potential of the high-side transmission line becomes higher than that of the low-side transmission line by ringing and a potential difference therebetween exceeds a forward drop voltage of the diode. As a result, a peak wave level of a positive side in the ringing is limited to the forward drop voltage of the diode.

摘要： A receiving device is provided capable of avoiding reception of unnecessary energy when a signal waveform actually changes on a receiving side. An impedance control circuit includes a sensing unit to sense one or more of a voltage, current, or power of a signal to be received by a receiving circuit. The impedance control unit varies an input impedance according to the change in the sensed one or more quantities so that the received signal will be reflected. Thus the excess energy of the signal is reflected and fed to any other receiving circuit achieving stable communications.
