CD4510
Up/Down counters are quite common components in logic circuits and applications. They count in binary as the clock changes from a low state to a high state, or from a high state to a low state. This up/down counter can be enabled on the preset pin, and you can also reset the counter by making the reset pin a logic high. You can also change the operation method to set the counter as an upward or downward counter by making the up/down pin (pin 10) a logic high or a logic low. It is however important not to leave this pin floating, otherwise the counter will not know in which way it should operate.
