    摘要: An integrated circuit (300/400) includes first and second power domains and a bank of input/output (I/O) cells (305/405) coupled to the first and second power domains. The bank of I/O cells (305/405) includes a first plurality of active clamps (374/445) for the first power domain and a second plurality of active clamps (384/425) for the second power domain wherein the first (374/445) and second (384/425) pluralities of active clamps overlap along the bank of I/O cells. According to one aspect each of the plurality of input/output cells (420, 440) has a bonding pad (421, 441) for receiving an output signal referenced to a respective first power domain, and at least one ESD protection element (425, 445) for a respective second power domain. According to another aspect, each of the plurality of input/output cells (420, 440) has a bonding pad (421, 441) for receiving a respective output signal and at least one ESD protection element for each of a first power domain and a second power domain.

    摘要: An electrostatic discharge (ESD) protected circuit is coupled to a power supply voltage rail and includes a multiple independent gate field effect transistor (MIGFET), a pre-driver, and a hot gate bias circuit. The MIGFET has a source/drain path coupled between an output pad and the power supply voltage rail and has a first gate terminal and a second gate terminal. The pre-driver circuit has an output. The hot gate bias circuit is coupled to the first gate terminal of the MIGFET, and the output of the pre-driver circuit is coupled to the second gate terminal of the MIGFET. The hot gate bias circuit is configured to apply a bias voltage to the first gate terminal of the MIGFET during an ESD event that increases the breakdown voltage of the MIGFET so as to better withstand the ESD event.

    摘要: An ESD protection circuit (81) and a method for providing ESD protection is provided. In some embodiments, an N-channel transistor (24), which can be ESD damaged, is selectively turned on and made conducting. The purpose of turning on the N-channel transistor (24) is to maximize the Vt1 of the N-channel transistor (24). Vt1 is the drain-to-source voltage point at which the parasitic bipolar action of the N-channel transistor (24) first occurs. In some embodiments, the ESD protection circuit (81) includes a diode (64) which provides an additional current path from the I/O pad 31 to a first power supply node (76).

    摘要: A modular bunk assembly or module provides for easy in situ installation of the bunk in an extended cab truck by compacting to a slab like profile for shipment and handling and easily expanding in the cab for installation. The bunk is readily adapted to provide attachment points corresponding to common attachment points for vehicle seats. The bunk further provides a readily reached storage area under a bed platform. Restraints may already be installed on the module when it is shipped to an automotive assembly plant.

    摘要: Resilient accommodation of vacuum brake booster check valves to vacuum source-generated pressure pulses tending to cause the valves to pulse open and close is accomplished by providing a resilient annular area in the check valve radially between its axial center and the area where it sealingly engages a valve seat when closed to inhibit valve pulsations and resulting valve noises generated by pulsations from the vacuum source.
