A bus driver is provided that can withstand over voltages being applied to its output terminal without the protection circuit detracting from the voltage swing that can be provided by the driver. The circuit arrangement also allows transistors having good on state resistance and large tolerance of drain-to-source voltages to be used.

Bus driver / line driver

A protection device is provided that exhibits a turn on time of order of one nanosecond or less. Such a device provides enhanced protection for integrated circuits against electrostatic discharge events. This in turn reduces the risk of device failure in use. The protection device can include a bipolar transistor structure connected between a node to be protected and a discharge path.
