Instructions for Use:
- Power Supply: Ensure the supply voltage (VCC) is within the specified range of 2.0V to 6.0V.
- Input Signals: Apply input voltages such that low inputs do not exceed 1.5V and high inputs are at least 3.5V for reliable operation.
- Output Load: Design circuits so that output currents comply with the limits ensuring VOL does not exceed 0.1V when sinking up to 4mA, and VOH remains above 4.9V when sourcing up to 0.4mA.
- Timing Considerations: Account for a propagation delay time of up to 18ns under standard conditions.
- Thermal Management: Monitor power dissipation; it should not exceed 100mW per package to prevent overheating.
Note: The 74HC02AF is a quad 2-input NOR gate. Always refer to the specific datasheet provided by the manufacturer for detailed specifications and application notes.
