The recommended operating voltage range for the HEF4081BT-Q100J is 4.5 V to 15 V.
The HEF4081BT-Q100J has a propagation delay time of 10 ns (typical) and a transition time of 5 ns (typical), making it suitable for moderate-frequency applications. However, for high-frequency applications, a faster logic family like the 74AHC or 74AHCT series may be more suitable.
To ensure the HEF4081BT-Q100J is properly powered, connect the VCC pin to a stable power supply voltage between 4.5 V and 15 V, and the GND pin to a reliable ground connection. Decouple the power supply with a 0.1 μF ceramic capacitor and a 10 μF electrolytic capacitor in parallel.
The HEF4081BT-Q100J is specified to operate from 4.5 V to 15 V, but it may still function at 3.3 V with reduced performance. However, Nexperia does not guarantee the device's performance at 3.3 V, and it is not recommended for new designs. For 3.3 V systems, consider using a 3.3 V-tolerant logic family like the 74LVC or 74LVCH series.
Unused inputs on the HEF4081BT-Q100J should be connected to a fixed logic level (VCC or GND) to prevent floating inputs, which can cause unpredictable behavior. Never leave unused inputs unconnected.
