ABSTRACT:
A circuit is provided for filtering asynchronous metastability. The circuit includes two or more output lines that provide signals indicative of the assertion of control or data input signals at a plurality of input lines. Despite the simultaneous assertion of two or more input signals, the circuit prevents the simultaneous assertion of more than one output signal, thereby preventing adverse effects within a digital system connected to the circuit.
