Instructions for SN74LS126AN

1. Supply Voltage (V_CC):

   • Ensure the supply voltage is within the range of 4.75V to 5.25V to avoid damage to the device.

2. Output Voltage Levels:

   • The output high voltage (V_OH) should be at least 2.4V when the output is high.
   • The output low voltage (V_OL) should not exceed 0.5V when the output is low.

3. Input Voltage Levels:

   • The input high voltage (V_IH) must be at least 2.0V to be recognized as a high input.
   • The input low voltage (V_IL) must not exceed 0.8V to be recognized as a low input.

4. Propagation Delay Time (t_pd):

   • The typical propagation delay time is 14 nanoseconds. This is the time it takes for the output to respond to a change in the input signal.

5. Power Dissipation (P_d):

   • The maximum power dissipation is 500 milliwatts. Ensure that the device does not exceed this limit to prevent overheating and potential damage.

6. Operating Temperature Range (T_A):

   • The device can operate in ambient temperatures ranging from -55°C to 125°C. Ensure that the operating environment stays within this range.

7. Storage Temperature Range (T_STG):

   • When storing the device, keep it within a temperature range of -65°C to 150°C to prevent damage.

8. 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 to prevent moisture damage.

9. Mounting and Soldering:

   • Follow recommended soldering profiles to ensure proper mounting and avoid thermal stress on the device.
   • Use appropriate tools and techniques to minimize the risk of physical damage during installation.

10. Testing and Troubleshooting:

    • Use a multimeter to verify the supply voltage and output levels.
    • If the device is not functioning correctly, check for proper connections, correct power supply, and input signals.
