Abstract: A power controlled input receiver, in accordance with the present invention, includes a receiver circuit including a first current source and a second current source. The first current source supplies current in a power down mode of the receiver and the second current source is enabled for supplying current in a normal operation mode. A signal state detection circuit is coupled to the receiver circuit for detecting an active input signal, and a control signal generator is coupled to the signal state detection circuit for generating an enable signal to enable the second current source when the active input signal is detected.
