Overvoltage protection circuits include a combination of an overvoltage detection circuit and a voltage clamping circuit that inhibits sustained overvoltage conditions. An overvoltage detection circuit can include first and second terminals electrically coupled to first and second power supply signal lines, respectively. This overvoltage detection circuit may be configured to generate a clamp activation signal (CAS) in response to detecting an excessive overvoltage between the first and second power supply signal lines. This CAS is provided to an input of the voltage clamping circuit, which is electrically coupled to the first power supply signal line and configured to sink current from the first power supply signal line in response to the CAS. The voltage clamping circuit may be configured to turn on and sink current from the first power supply signal line in-sync with a transition of the CAS from a first logic state to a second logic state.

A packet switch includes a pointer table for mapping locations in an input data buffer to locations in an output data buffer. The processor generates an output data packet based on data portions in the input data buffer and based on the pointer table. The output data buffer stores data portions of the output data packet successively in a sequential order and can output the data portions of the output data packet successively in a sequential order. The pointer table may be configured to reduce the latency or reduce the power consumption of the packet switch.
