The recommended operating voltage range for CD4042BF3A is 3V to 18V, although it can operate from 2V to 20V with reduced performance.
To ensure proper power-on and power-off, connect a 0.1uF to 1uF capacitor between VCC and GND, and a 1kΩ to 10kΩ pull-up resistor between VCC and the enable pin (if used).
The CD4042BF3A can handle clock frequencies up to 10MHz, but the maximum frequency may vary depending on the specific application and operating conditions.
To implement a reset function, connect the reset pin (R) to VCC through a 1kΩ to 10kΩ resistor, and then connect the reset pin to GND through a 0.1uF to 1uF capacitor. This will ensure a clean reset signal.
The enable pin (E) is used to enable or disable the clock signal. When the enable pin is high, the clock signal is enabled, and when it's low, the clock signal is disabled.
