摘要： A load adaptive pad driver for integrated circuits provides a substantially constant speed output at the pad regardless of the load connected to the pad. A reference slope signal, based on variables such as fabrication process, and operational voltage and temperature ranges and biased to give a substantially flat response, is compared to the signal output of a resistive-based pad driver circuit. When a transition between output signal levels provided by the pad driver circuit is slower than the reference signal slope, an auxiliary driver circuit is used to compensate. Electromagnetic interference is also reduced via said load adaptive pad driver.

摘要： A first electronic device, such as a computer, is connected to a second electronic device, such as a printer, over a communication bus. The second electronic device has device specific integrated circuitry for performing the functions of the device, and also has pad driver circuitry. The pad driver circuitry is connected between the communication bus and the device specific integrated circuitry. The first electronic device is powered by a first voltage source, such as AC power through an on/off switch. The second electronic device is powered by a second voltage source, such as AC power through a different on/off switch. In addition to being powered by the second voltage source, the pad driver circuitry is also powered by a third voltage source, isolated from the second voltage source. When the pad driver circuitry in the second device detects that the first device is powered-on and the second device is powered-off, it assures that the device specific circuitry in the second device will not become inadvertently powered-on by the first device through the communications bus. Pad driver circuitry also assures that power from the first device through a data line on the communications bus is not inadvertently fed back to the first device through a different data line on the communications bus. Pad driver circuitry also assures that current from the first device is not sunk (i.e. finds a path to ground) through the pad driver circuitry.
摘要翻译：诸如计算机的第一电子设备通过通信总线连接到诸如打印机的第二电子设备。第二电子设备具有用于执行设备功能的设备专用集成电路，并且还具有焊盘驱动器电路。焊盘驱动器电路连接在通信总线和设备专用集成电路之间。第一个电子设备由第一电压源供电，例如通过开/关开关的交流电源。第二电子设备由诸如通过不同开/关开关的AC电力的第二电压源供电。除了由第二电压源供电之外，焊盘驱动器电路还由与第二电压源隔离的第三电压源供电。当第二设备中的焊盘驱动器电路检测到第一设备通电并且第二设备断电时，它确保第二设备中的设备专用电路不会被第一设备通过通讯总线。焊盘驱动器电路还确保来自第一设备的电力通过通信总线上的数据线不会被无意地通过通信总线上的不同数据线反馈到第一设备。焊盘驱动器电路还确保来自第一器件的电流不会通过焊盘驱动器电路沉没（即，找到接地的路径）。
