    Can anyone point me to a website which highlights a Digital Clock Circuit
    design using 7400 TTL series chips?


    I plan to have 'hours', 'minutes', and 'seconds' on this clock.



    Thanks,

    Lance
     
  2. Man, it's so easy to build one... Use the 4511 (counter + latch), and a
    few of logical gates will help you to increase minutes after 60 seconds,
    etc...

    There is a digital clock using the newer 74HC parts here:

    http://ourworld.compuserve.com/homepages/Bill_Bowden/dclock.htm

    The basic clock uses 7 ICs and the display uses another 5.
    Two of the display digits are multiplexed for minutes or
    seconds so you only need 4 digits for hours, minutes and seconds.
