The CD54HC93F3A is a high-speed CMOS 4-bit binary counter. It is a synchronous counter, meaning all flip-flops are clocked simultaneously, allowing for predictable and reliable operation. This device is part of the 54HC series, known for its high noise immunity and low power consumption, making it suitable for various digital logic applications.

Applications:

• Frequency dividers
• Digital clocks and timers
• Address counters for memory systems
• Event counters
• Control circuits

Features:

• Synchronous counting operation
• High-speed CMOS logic
• 4-bit binary counting
• Individual clear input
• Cascadable for higher-order counters
• Wide operating voltage range

Benefits:

• Precise and predictable counting due to synchronous operation
• Low power consumption, suitable for battery-powered applications
• High noise immunity, ensuring reliable operation in noisy environments
• Flexibility in counting range through cascading
• Easy to clear the counter to a known state

The CD54HC93F3A consists of four master-slave flip-flops internally interconnected to provide a divide-by-two section and a divide-by-eight section. These sections are triggered by a clock input and can be used independently or connected to form a divide-by-sixteen counter. The device also features a clear input that resets all flip-flops to a low state. The synchronous operation ensures that all outputs change state simultaneously, eliminating glitches and ensuring accurate counting. Its high-speed performance allows it to be used in applications requiring fast counting rates. The wide operating voltage range enhances its compatibility with different power supplies. The ability to cascade multiple devices allows for the creation of counters with larger counting ranges.
