Abstract
A current steering switch circuit responsive to a CMOS signal. In an specific embodiment the switch is incorporated in a hybrid BiCMOS multiplexer circuit using combined CMOS and CML/ECL signal types. The high speed CML/ECL logic signals are multiplexed under the control of a lower speed CMOS signal. A particular aspect of the circuit is that a CMOS to CML/ECL converter is not used. Additionally, a differential, logic commutation signal is not required.
