A substantially noise-free address input buffer for an asynchronous device, such as a static random access memory (SRAM). The input buffer generates both a logical true and complement representation of an address input signal and includes timing circuitry to place the logical true and complement signals in the same deasserting logical state for a predetermined period of time prior to asserting either the logical true signal or the logical complement signal, in response to a signal edge transition appearing on the address input signal. The input buffer further includes edge transition detection (ETD) circuitry for generating an initialization signal in response to the generation of the logical true and complement signals.
