Instructions for Use:

1. Power Supply Connection:

   • Connect the supply voltage (Vcc) between 3V and 5.5V to the appropriate pins.
   • Ensure proper decoupling capacitors are placed close to the supply pins to minimize noise.

2. Input Monitoring:

   • Connect the input signal to be monitored to the IN pin. Ensure the input voltage does not exceed the specified range (-0.3V to 26V).

3. Output Configuration:

   • The output is an open-collector configuration, which requires an external pull-up resistor to a suitable voltage level.

4. Shutdown Control:

   • To put the device into shutdown mode, apply a low signal to the SHDN pin. This reduces the supply current to approximately 1μA.

5. Comparator Operation:

   • The comparator compares the input voltage against the internal reference (1.24V). The output will go low when the input voltage exceeds this threshold.

6. Thermal Considerations:

   • Ensure the device operates within its specified temperature range (-40°C to 85°C) for reliable performance.

7. Handling Precautions:

   • Follow standard ESD handling precautions to avoid damage to the device.

8. Storage Conditions:

   • Store the device in a dry environment within the temperature range of -65°C to 150°C.
