Instructions for Use

1. Supply Voltage:

   • Ensure the supply voltage (V_CC) is within the range of 4.5V to 5.5V. Exceeding this range can damage the device.

2. Output Current:

   • The output current when high (I_OH) is typically 30mA, and when low (I_OL) is typically 15mA. Design your load accordingly to avoid exceeding these limits.

3. Input Voltage:

   • The input voltage for a high state (V_IH) should be between 2.0V and 5.5V, and for a low state (V_IL) should be between 0V and 0.8V.

4. Power Dissipation:

   • The maximum power dissipation (P_D) is 625mW at room temperature (25°C). Ensure adequate heat dissipation if operating near this limit.

5. Temperature Range:

   • The operating temperature range (Ta) is from -40°C to 125°C. The storage temperature range (Tstg) is from -65°C to 150°C. Avoid exposing the device to temperatures outside these ranges.

6. Handling:

   • Handle the device with care to avoid static discharge, which can damage the internal components. Use proper ESD protection measures.

7. Mounting:

   • Ensure the device is securely mounted on the PCB with appropriate soldering techniques to maintain reliable electrical connections.

8. Testing:

   • Before final assembly, test the device under typical operating conditions to ensure it meets the specified parameters.

9. Compliance:

   • Ensure that the device complies with all relevant safety and regulatory standards for your application.
