Power Supply Connection: Connect the supply voltage (VCC) between 2V and 6V. Ensure a stable power supply to avoid malfunction.
Input Signals: Apply input signals within the specified range for VI(L) and VI(H). Inputs should be driven by compatible logic levels.
Output Load: Outputs can sink or source up to 4 mA. Ensure connected loads do not exceed this current limit.
Propagation Delay: The propagation delay is critical for timing considerations in digital circuits. Design with a maximum delay of 17 ns at typical conditions.
Thermal Management: Keep the operating temperature within -40掳C to 85掳C. Consider heat dissipation if used in high-density designs.
Handling Precautions: Handle the device carefully to prevent electrostatic discharge (ESD) damage. Follow anti-static precautions during assembly and testing.
Storage: Store in a dry, cool place away from direct sunlight and corrosive materials.
