Pin Count: 5
Functions of the Pins:
1. VCC: This is the supply voltage input pin. It is where the voltage being monitored is connected.
2. GND: Ground pin. This is the reference point for all voltages in the circuit.
3. RESET: An active-low reset output pin. It goes low when VCC falls below a certain threshold and stays low for a specified delay time after the voltage returns above the threshold.
4. MR: Manual reset input. When held low, it manually forces the reset output to go low.
5. NC: No connection. This pin is typically not connected internally and can be left floating or connected to ground.
