The CD4067BE can operate up to 5 MHz, but the maximum frequency of operation depends on the specific application and the quality of the clock signal.
To ensure proper power sequencing, the VCC pin should be powered up before the clock signal is applied, and the VCC pin should be powered down after the clock signal is removed.
The recommended operating voltage range for the CD4067BE is 3V to 15V, but it can operate as low as 2V with reduced performance.
To minimize power consumption, use a low-frequency clock signal, reduce the voltage supply, and use a low-power mode if available.
The maximum current rating for the CD4067BE is 1mA per output, but this can be increased by using an external buffer or amplifier.
