    Hi, i need a decade counter which can count in both up & down modes.
    I searched on the net. But im not satisfied with those. I need an IC with a pin for up/down modes. If the pin is enabled, it has 2 work in one mode(up/down). And if it is disabled, it should work in the other mode.
    For a triggering pulse, that ic should count from 0~9 and in the other mode for the same triggering it should count from 9~0.

    Is there any IC available with these features?

    Check out the CMOS chip 4029, I think you'll find it meets your needs.
