    I went looking for IC CD40110BE Electronic shop they have only CD4028BE, I down loaded a up down counter circuit from the internet this circuit is build with using CD40110BE, I am not an expert I am a hobbyist. I would like to know instead of CD40110BE whether I can use CD4028BE.Hope some one can advise regarding this.

    Any link to circuit from the net? But as far as I understand. Using the 4028 instead of 4011 will not work very good

    No. The 4028 accepts BCD inputs and toggles a single pin in reference to the BCD value. The 40110 accepts a clock signal and outputs to a 7-segment display.

    If you don't have access to a 40110, you can use a CD4510 with a CD4511 or CD4543. The 4510 accepts a clock signal and outputs BCD. The 4511 or 4543 accept BCD and output to a 7-segment display.

    The 4510 offers one feature not found in the 40110: you can preset the value. In other words, if you want the display to show a specific number at a given time, you can set the preset BCD values and toggle the preset pin. This is useful for clocks when you want to reset the tens place, e.g., 59 to 00, 12 to 1, etc.

    Now, if you only want to count up (never down), you could get away with the CD4026 or the CD4033. Like the 40110, these take a clock signal and output to a 7-segment display.
