    Rev: Title: Document Number: Cmos Clock

    Uploaded by

    SRIKANTH
    This document contains a circuit diagram for a CMOS clock. The clock uses integrated circuits such as 4011N, 4518N, and 4093N logic gates connected with resistors and capacitors to generate time signals. Oscillations from a 32.768 kHz crystal control timing functions. The clock outputs hours, minutes and run/set signals.
