About this product
The 74LS390 is a TTL dual decade counter with two independent sections, each providing a divide-by-2 and a divide-by-5 stage. The stages can be cascaded to form a divide-by-10 BCD counter, and reset inputs clear the counters. It is used for frequency division and simple digital counting in 5 V circuits.

How do I make a divide-by-10 counter with the 74LS390?
Feed the input signal into CLKA and connect output QA to CLKB. This gives a divide-by-2 stage followed by a divide-by-5 stage, producing a BCD count from 0 to 9 on QA to QD.
How do I reset the counter?
Both reset inputs of a section (MR1 and MR2) are active high. Setting both high clears that section's outputs to zero, so bring them low again to resume counting.
