The maximum clock frequency for the M74HC4017B1R is 25 MHz, but it can vary depending on the operating voltage and temperature. It's recommended to check the datasheet for specific frequency limits at different operating conditions.
To ensure proper reset, the reset pin (MR) should be pulled low for at least 2 clock cycles. Additionally, the clock pin (CP) should be low during reset to prevent counting during the reset period.
Yes, the M74HC4017B1R can be used as a synchronous counter. The counter will increment on the rising edge of the clock signal, and the output will be updated simultaneously.
The propagation delay time for the M74HC4017B1R is typically around 10-15 ns, but it can vary depending on the operating voltage and temperature. Check the datasheet for specific propagation delay times at different operating conditions.
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 reached its maximum count. The CO pin can be connected to the clock pin of another counter to create a multi-stage counter.
