The CD 4040 is a 12 stage binary counter.
Each output divides the frequency delivered to the clock-line, by 2.
The maximum division is 4096. The output goes high after 2048 cycles and
then low after another
When the Reset line is
taken HIGH, all outputs become LOW.
4040 is a CMOS chip.
Minimum supply voltage 6v
Maximum supply voltage 15v
Max current per output 15mA
Maximum speed of operation 5MHz
