CD4518BPWR Description

The CD4518BPWR from Texas Instruments is a dual 4-bit BCD (Binary-Coded Decimal) counter belonging to the 4000B series, designed for high-reliability digital counting applications. This synchronous, up-counter operates over a wide voltage range (3V to 18V), making it versatile for both low-power and industrial systems. Packaged in a 16-pin TSSOP with tape-and-reel (TR) delivery, it is optimized for surface-mount assembly and complies with ROHS3 and REACH environmental standards. Its dual-element design (two independent counters) and 8 MHz count rate ensure efficient performance in timing and sequencing circuits.

CD4518BPWR Features

• Dual 4-bit BCD counters with synchronous operation for precise timing control.
• Wide supply voltage range (3V–18V), supporting compatibility with TTL and CMOS logic levels.
• Flexible triggering: Counts on positive or negative clock edges, enhancing design adaptability.
• Asynchronous reset for immediate counter clearing without clock dependency.
• High noise immunity and low power consumption, typical of the 4000B series.
• Surface-mount (TSSOP-16) packaging, ideal for space-constrained PCB designs.
• Moisture Sensitivity Level (MSL) 1, suitable for extended storage and handling.

CD4518BPWR Applications

The CD4518BPWR excels in applications requiring accurate counting, frequency division, or time-delay generation, such as:

• Industrial control systems: Event counting in PLCs and automation equipment.
• Consumer electronics: Digital clocks, timers, and appliance control circuits.
• Instrumentation: Frequency meters and data acquisition systems.
• Automotive electronics: Odometer and dashboard display drivers.
• Embedded systems: Low-power microcontroller-based projects.

Conclusion of CD4518BPWR

The CD4518BPWR stands out for its dual-counter architecture, wide voltage range, and robust noise immunity, making it a superior choice for BCD counting applications. Its synchronous operation and asynchronous reset provide design flexibility, while the TSSOP package ensures compact integration. Whether for industrial, automotive, or consumer electronics, this IC delivers reliable performance in demanding environments, backed by Texas Instruments' quality assurance.
