The function of an IC 7490 Decade Counter, which is a computer chip, is to pin cycles 0 to 9 through QA, QB, QC and QD which are 4 bits in a binary number. The IC 7490 Decade Counter produces an output pulse for every ten input pulses.
Likewise, if we wanted to count from 0 up to 999 (0000 0000 0000 to 1001 1001 1001), then three cascaded decade counters are required. In fact, multiple decade counters can be constructed simply by cascading together individual BCD counter circuits, one for each decade as shown. 2-digit BCD Counter from 00 to 99
connect Q3 to both reset pins
