Product Overview: NXP HEF4520BP Dual Binary Counter

The NXP HEF4520BP is a robust, high-performance CMOS Dual Binary Counter integrated circuit designed to cater to a wide range of counting applications in the electronics industry. This precision-engineered component is part of NXP's HEF4000 series, which is renowned for its reliability and versatility in various digital systems.

Key Features

• Dual 4-bit Counter: The HEF4520BP consists of two independent 4-bit binary counters, each with a master reset input. This allows for flexible configurations, such as cascading for an 8-bit counter or operating two separate counting sequences.
• Wide Voltage Range: It operates over a wide supply voltage range from 3V to 15V, making it suitable for battery-operated devices as well as for standard TTL and CMOS levels, ensuring compatibility with various circuit designs.
• High Noise Immunity: The HEF4520BP exhibits high noise immunity and low power consumption, characteristics that are essential for stable and efficient operation in electrically noisy environments.
• Synchronous Counting: Both counters are negative edge-triggered and count synchronously. Synchronous operation provides accurate counting sequences with no propagation delay between the stages.
• Reset Function: The master reset input allows the user to reset the counter to zero, which is essential for precise control over counting operations.
• Output Capability: The standard 4000B output drive provides the capability to drive TTL loads over the full VDD to VSS supply voltage range.
