STMicroelectronics HCF4518BEY is a dual 4-bit BCD counter from the 4000B series. This synchronous counter features two independent BCD counter elements, each capable of counting up to 9999. The device operates with a maximum count rate of 8 MHz. Reset functionality is asynchronous, allowing for immediate clearing of the counter states. It supports both positive and negative edge triggering for counting operations. The HCF4518BEY is designed for a wide supply voltage range of 3V to 20V and operates across an extended temperature range of -55°C to 125°C. Packaged in a 16-DIP form factor, this component is suitable for through-hole mounting. Applications include digital logic systems, frequency division, and control circuits within industrial automation and consumer electronics.
