Instructions for TC74VHC02FT

1. Power Supply: Ensure the supply voltage (VCC) is within the range of 2.0V to 5.5V.
2. Input Signals: For reliable operation, input signals should be below 0.8V for a low logic level and above 2.0V for a high logic level.
3. Output Levels: The output will provide a low level not exceeding 0.1V when sourcing up to 4mA, and a high level of at least 4.5V when sinking up to 4mA.
4. Propagation Delay: Expect a typical propagation delay of 6ns under standard conditions (VCC=5V, ambient temperature=25掳C).
5. Power Consumption: The device consumes approximately 1渭A at an operating frequency of 10MHz.
6. Handling Precautions: Handle with care to avoid damage from electrostatic discharge (ESD). Use appropriate ESD protection measures during handling and installation.
7. Operating Temperature: Ensure the device operates within its specified temperature range to maintain reliability and performance.
