Additional Details

The UPD74HC4040GS advances one count on the negative-going transition of the clock input. A HIGH level on the Reset input returns all counter outputs (Q0-Q11) to a low level. The counter does not have any clock enable inputs; it continuously counts as long as the clock input is toggling. The outputs are standard CMOS outputs, capable of driving moderate loads.

This device is commonly available in a SOIC (Small Outline Integrated Circuit) package.
