Detailed Specs

The TC74HC4518P features two independent 4-stage binary counters, each capable of counting up to 15. The counters are synchronous, meaning that all flip-flops change state simultaneously on the rising edge of the clock pulse. This ensures accurate and predictable counting. The high-speed CMOS logic provides fast switching speeds and low power consumption. Each counter has a reset input that clears the counter to zero, and a clock enable input that allows the counter to be enabled or disabled. The TC74HC4518P is commonly used in frequency dividers, timers, and control circuits where accurate counting is required. Toshiba Semiconductor and Storage CMOS logic devices are known for their reliability and performance. The TC74HC4518P simplifies digital system design by providing two independent counters in a single package. Its synchronous operation and reset and clock enable inputs provide flexibility in various counting applications. The specific details of propagation delays, voltage requirements, and pin configurations are available in the product datasheet. This part is a staple for building digital systems and performing counting or timing operations. The HC family generally offers a good compromise between speed and power consumption.
