The CD4015BE can handle clock frequencies up to 10 MHz.
To ensure proper reset, connect the Reset (R) pin to VCC through a 1kΩ resistor and a 10nF capacitor to ground. This will ensure that the device is properly reset during power-up.
The recommended operating voltage range for the CD4015BE is 5V ± 10%.
The CD4015BE 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 CD4015BE is 10 Mbps.
