Abstract
IC input circuitry particularly suited for use in an electronic wristwatch or other small-sized electronic instrument is provided. Each input stage is adapted to receive at least one input. An input terminal is provided for each input stage in order to receive a two-state input signal. An impedance element is disposed intermediate each input terminal and a reference voltage, in order to distinguish between respective states of the input signal. The invention is particularly characterized by gating circuitry for producing a gating signal having a predetermined time interval, and a memory, coupled to each input terminal and impedance element coupled thereto, for selectively storing the state of the input signal applied to the input terminal and discriminated by the impedance element, during the predetermined time interval of the gating signal.
