The maximum frequency of operation for the HEF4067BT,652 is 10 MHz, but it can be limited by the propagation delay and rise/fall times of the device.
To ensure proper switching, make sure to provide a valid logic level (VDD or GND) to the control inputs (S1-S4) and maintain a minimum voltage difference of 2V between VDD and VSS. Also, ensure that the input signals are within the recommended voltage range.
The maximum voltage that can be applied to the analog inputs is VDD + 0.5V, but it's recommended to keep it within the VDD and VSS rails to prevent damage to the device.
While the HEF4067BT,652 is primarily designed as an analog switch, it can be used as a digital switch in certain applications. However, keep in mind that the device's propagation delay and rise/fall times may affect digital signal integrity.
To minimize power consumption, ensure that the device is operated within the recommended voltage range, and consider using a lower supply voltage (VDD) if possible. Additionally, use a high-impedance input signal to reduce current consumption.
