Instructions for Use:

1. Power Supply Connection: Connect the supply voltage to the VCC pin and ensure it is within the specified range of 1.6V to 5.5V.
2. Ground Connection: Connect the GND pin to the system ground.
3. Reset Input: The MR (Manual Reset) pin can be pulled low to activate the reset function manually. It should be connected to a pull-up resistor when not in use.
4. Output Handling: The output pin (OUT) is open-drain and requires a pull-up resistor to the supply voltage. This pin will go low when the input voltage drops below the reset threshold.
5. Capacitor Placement: Place a bypass capacitor close to the VCC and GND pins to stabilize the supply voltage.
6. Temperature Considerations: Ensure the device operates within the temperature range of -40掳C to +85掳C for reliable performance.
7. PCB Layout: Keep the layout compact to minimize noise and improve performance, especially around the power and ground connections.
