CD4518BNS

The CD4518BNS is a dual BCD (Binary-Coded Decimal) up-counter designed to operate over a wide range of supply voltages and is part of the CD4000 series of integrated circuits. It includes two separate counter circuits, each with a count-enable input, a carry-out output, and a reset input. The counters advance on the positive edge of the clock input, and each can independently count from 0 to 9 before resetting to 0 and generating a carry-out signal, which can be used to cascade multiple counters for higher count ranges.
This IC is typically used in digital applications where accurate counting is required, such as in digital clocks, frequency counters, and event counters. Key features include low power consumption, high noise immunity, and the ability to operate in both synchronous and asynchronous modes. The CD4518BNS is compatible with other TTL, CMOS, and NMOS logic families, making it versatile for various digital projects. It is commonly packaged in a standard DIP (dual in-line package), suitable for prototyping and easy integration on breadboards or PCBs.

The CD4518BNS is a dual BCD up-counter integrated circuit. It features a total of 16 pins. Each counter within the IC is a 4-bit BCD counter, and the chip contains two of these counters, hence the term "dual."
Here is a brief overview of the pin functions:
1. VDD (Pin 16): Positive power supply.
2. VSS (Pin 8): Ground.
3. A Counter:
- Pins 1-4 (Q1A-Q4A): Output pins for the A counter, representing the 4-bit BCD output.
- Pin 5 (CP0A): Clock input for the A counter.
- Pin 6 (MR A): Master reset for the A counter, active high.
4. B Counter:
- Pins 10-13 (Q1B-Q4B): Output pins for the B counter, representing the 4-bit BCD output.
- Pin 9 (CP0B): Clock input for the B counter.
- Pin 7 (MR B): Master reset for the B counter, active high.
The counters increment on the positive edge of the clock input, and the master reset clears the counter to zero when activated.
