The recommended operating voltage range for the HCF4081BM1 is 4.5V to 15.5V, although it can operate from 3V to 18V with reduced performance.
To ensure proper power-on and power-off, it is recommended to use a slow-rising power supply voltage (typically 10ms to 100ms) and to avoid voltage spikes or dips during power-on and power-off transitions.
The maximum frequency of operation for the HCF4081BM1 is typically 10MHz, although it can operate at higher frequencies with reduced performance and increased power consumption.
To handle thermal management, it is recommended to provide adequate heat sinking, use a thermally conductive package, and ensure good airflow around the device. The maximum junction temperature (Tj) is 150°C.
The input impedance of the HCF4081BM1 is typically around 1kΩ to 10kΩ, depending on the input voltage and frequency.
