1. A controller area network (CAN) transmitter, comprising:
an output stage circuit including a CANH port and a CANL port;
an input stage circuit to receive an input signal, the input signal to indicate whether the output stage circuit is to provide dominant or recessive states;
a first cascode circuit to provide output signals on the output stage circuit to provide dominant or recessive states based on the input signal;
a first switch circuit to, based upon the input signal, switch the first cascode circuit on and off;
a second cascode circuit configured to provide output signals on the output stage circuit to provide dominant or recessive states based on the input signal; and
a second switch circuit configured to, based upon the input signal, switch the second cascode circuit on and off;
wherein the first switch circuit and second switch circuit are to, based upon an indication from the input signal to output a recessive state, switch off the first cascode circuit and the second cascode circuit to short-circuit sources of the first cascode circuit and the second cascode circuit.
