The maximum frequency of operation for the HEF4016BP is 10 MHz, but it can be operated at higher frequencies with reduced voltage and current.
To ensure proper power supply, connect the VCC pin to a stable 5V power supply, and the VSS pin to ground. Also, decouple the power supply with a 100nF capacitor.
The HEF4016BP can sink or source up to 20mA of current per output pin, but it's recommended to limit the current to 10mA to ensure reliable operation.
Unused inputs should be connected to VCC or VSS to prevent them from floating, which can cause unpredictable behavior.
The HEF4016BP is rated for operation up to 70°C, but it can be operated at higher temperatures with reduced reliability and performance.
