Abstract:
An integrated circuit includes an output driver circuit having first and second transistors coupled to an external pad of the integrated circuit and first and second multiplexer circuits. The first multiplexer circuit is configurable to cause the first transistor to be controlled by a first voltage during a data output mode of operation and to couple a first control input of the first transistor to the external pad during a hot-socket protection mode of operation. The second multiplexer circuit is configurable to cause the second transistor to be controlled by a second voltage during the data output mode of operation and to couple a second control input of the second transistor to the external pad during the hot-socket protection mode of operation.
