4 Digit Up/Down Counter Kit

This is a low cost 4-digit Up/Down counter. Count range is from 0000, 1, 2 … to 9999 (counting up) or 0000, 9999, 9998, …. 0001 (counting down). The Overflow output pulses low when the count wraps around to zero. This output allows two counters to be connected together to make an 8 digit counter. The counter should really be only used for counting up or down in any particular application. However, if you know the count will not get near 9000 then you could connect the DOWN pins as required so that combined up/down readings will be summed.
