Product data sheet
Remark: It is essential not to enable the counter on CP1 when CP0 is HIGH, or on CP0
when CP1 is LOW, as this would cause an extra count.
Figure 13
74HC4017; 74HCT4017. Since the 74HC4017; 74HCT4017 has an asynchronous reset,
the output pulse widths are narrow (minimum expected pulse width is 6 ns). The output
pulse widths can be enlarged by inserting an RC network at the MR input.
