Instructions for Use:
Supply Voltage:
- Ensure the supply voltage (VCC) is within the range of 4.75V to 5.25V to avoid damage to the device.
Input Voltages:
- High-level input voltage (VIH) should be at least 3.15V to ensure proper logic high recognition.
- Low-level input voltage (VIL) should not exceed 0.85V to ensure proper logic low recognition.
Output Voltages:
- High-level output voltage (VOH) will be at least 2.7V under typical conditions.
- Low-level output voltage (VOL) will be no more than 0.4V under typical conditions.
Current Ratings:
- Input currents (IIH and IIL) should be within the specified limits to prevent damage.
- Output currents (IOH and IOL) should also be within the specified limits to avoid overheating or damage.
Propagation Delay:
- The propagation delay time (tpd) is the time it takes for a change in input to affect the output. It ranges from 9ns to 36ns, depending on the specific operating conditions.
Power Dissipation:
- The total power dissipation (PTOT) should not exceed 500mW to avoid overheating and potential failure of the device.
Handling and Storage:
- Handle the device with care to avoid static discharge, which can damage the internal circuits.
- Store the device in a dry, cool place away from direct sunlight and extreme temperatures.
Mounting:
- Ensure proper mounting and soldering techniques to avoid mechanical stress and ensure good electrical connections.
By following these parameters and instructions, you can ensure reliable operation of the HD74LS40P.
