The HD74HC4520FPEL-E is a high-speed CMOS dual binary counter manufactured by Renesas Electronics America. This device consists of two independent 4-stage binary counters, each with individual clock, reset, and enable inputs. It's primarily used for frequency division, timing, and counting applications in digital systems. The cascading capabilities of the counters allow for the implementation of larger counting ranges.

Applications:

• Frequency dividers
• Timers and chronographs
• Digital counters
• Sequencers
• Address decoders
• Control circuits

Features:

• High-speed operation
• Dual 4-stage binary counters
• Individual clock, reset, and enable inputs for each counter
• Cascadable for larger counting ranges
• Low power dissipation
• Wide operating voltage range
• TTL compatible inputs

Benefits:

• Provides accurate frequency division and timing capabilities.
• Reduces component count and simplifies circuit design.
• Offers flexible counting options with individual control inputs.
• Enables the implementation of large counting ranges through cascading.
• Low power consumption minimizes energy usage.
• Simple interface with TTL compatible inputs.

Additional Details:

The HD74HC4520FPEL-E is available in a 16-pin SOP (Small Outline Package). Each counter increments on the positive-going transition of its clock input, provided that the enable input is low. A high level on the reset input asynchronously clears the counter. The device's CMOS technology ensures low power consumption and high noise immunity. It operates over a wide voltage range, typically 2V to 6V. The maximum clock frequency can reach up to 30 MHz at 5V. The device is well-suited for use in battery-powered devices and other low-power applications. The 'FPEL' suffix indicates a specific packaging and environmental compliance standard, likely including lead-free construction. This part is commonly used in applications where a precise division of frequency is needed such as test equipment, signal generators, and embedded control systems.
