Patent ID: 8217681

Claim:
An input circuit ( 3 ) of an electronic computer ( 4 ) of a motor vehicle comprising at least one input port ( 2 ) comprising an input line ( 20 ) designed to be coupled to a peripheral device ( 5 ) of said electronic computer: a plurality of pull-up loads ( 230 a ), each pull-up load being coupled to a power supply line ( 21 ) and to the input line ( 20 ) and comprising at least one transistor ( 231 a ) forming a current mirror with a first current reference module ( 232 a ), a plurality of pull-down loads ( 230 b ), each pull-down load being coupled to a ground line ( 22 ) and to the input line ( 20 ) and comprising at least one transistor ( 231 b ) forming a current mirror with a second current reference module ( 232 b ), each pull-up load ( 230 a ) and each pull-down load ( 230 b ) comprising a switch ( 233 a , 233 b ), a closure that individually activates an associated one of the pull-up load ( 230 a ) and the pull-down load ( 230 b ), the input port ( 2 ) being configurable by ordering the closure or opening of each switch ( 233 a , 233 b ), a first reference current source ( 30 ) coupled to the first current reference module ( 232 a ) of the at least one input port ( 2 ), a second reference current source ( 30 ) coupled to the second current reference module ( 232 b ) of the at least one input port ( 2 ), configuration means for the at least one input port.
