The recommended operating voltage range for the CD40103BE is 3V to 15V, although it can operate as low as 2V with reduced performance.
To ensure proper power-on and power-off, it's recommended to use a capacitor between VCC and GND, and to sequence the power-on and power-off of the VCC and clock signals.
The maximum clock frequency that the CD40103BE can handle is 10 MHz, although it can operate at higher frequencies with reduced performance.
The asynchronous reset input (MR) should be tied to VCC through a resistor and a capacitor to ensure proper reset operation.
The Q7 output of the CD40103BE is an overflow output that goes high when the counter overflows, indicating that the count has reached its maximum value.
