The CD4015BM can handle clock frequencies up to 10 MHz.
To ensure proper reset, connect the Reset (R) pin to VCC through a 1 kΩ resistor and a 10 nF capacitor to ground. This will ensure that the device is properly reset during power-up.
The recommended operating voltage range for the CD4015BM is 5V ± 10%.
The CD4015BM can be interfaced with a microcontroller using a serial interface. Connect the Clock (CLK) pin to the microcontroller's clock output, and the Data (D) pin to the microcontroller's data output.
The maximum data transfer rate of the CD4015BM is 10 Mbps.
