Patent ID: 7304526

Claim:
A switch comprising: a first transistor with main electrodes constituting in/outputs of the switch and with a control electrode constituting a first control input of the switch for in response to a first control signal controlling the first transistor; a second transistor with main electrodes constituting the in/outputs of the switch and with a control electrode constituting a second control input of the switch for in response to a second control signal controlling the second transistor; and a circuit for in response to the first control signal and an in/output signal at an in/output of the switch generating the second control signal, wherein the circuit comprises a generator for, in an enable mode with the first control signal having a first value, generating the second control signal having a second value; wherein the generator comprises a third and a fourth transistor of which first main electrodes are coupled to each other and second main electrodes are coupled to each other, which first main electrodes are further coupled to a first main electrode of a fifth transistor which second main electrodes are further coupled to first main electrodes of a sixth seventh and eighth transistor for generating the second control signal with a control electrode of the third transistor being coupled to first main electrodes of a ninth and a tenth transistor, with second main electrodes of the seventh eighth and tenth transistor being coupled to each other, with a control electrode of the seventh transistor being coupled to the first main electrode of the seventh transistor and with control electrodes of the fifth sixth ninth and tenth transistor receiving the first control signal or a derived version thereof.
