The recommended operating voltage range for the CD54HCT14F3A is 4.5V to 5.5V.
To ensure proper power supply, connect VCC to a stable 5V power source and GND to a reliable ground connection. Decouple the power supply with a 0.1uF capacitor to reduce noise.
The maximum frequency of operation for the CD54HCT14F3A is 30MHz.
Unused inputs should be tied to VCC or GND through a 1kΩ resistor to prevent floating inputs and reduce noise.
The maximum output current of the CD54HCT14F3A is 4mA per output pin.
