The 74HC4060D can handle clock frequencies up to 30 MHz.
The counter can be reset by applying a low pulse to the reset input (RST) pin.
The carry-out (CO) pin is used to cascade multiple counters. When the counter overflows, the CO pin goes high, indicating that the counter has overflowed.
Yes, the 74HC4060D can be used as a frequency divider by connecting the clock input to the clock output of a previous stage, and using the divided clock output as the input to the next stage.
To ensure that the counter starts counting from zero, apply a low pulse to the reset input (RST) pin before applying the clock signal.
