This disclosure provides examples of circuits, devices, systems, and methods for providing high speed operation with high noise immunity. In one implementation, a circuit includes a first buffer configured to receive an incoming signal and to generate a first output signal. The circuit also includes a second buffer configured to receive the incoming signal and to generate a second output signal. The second buffer exhibits hysteresis with lower and upper thresholds. The circuit also includes an output block configured to receive the first and second output signals and to generate a third output signal. The output block is configured to switch a logic state of the third output signal in response to a transition of a logic state of the first output signal, and to lock the logic state of the third output signal until the output block receives a transition of a logic state of the second output signal. |
