Applications:

• Frequency dividers
• Address counters for memory systems
• Control circuits
• Timing circuits
• Digital data processing systems

Features:

• Synchronous counting and loading
• High-speed operation
• Carry look-ahead for easy cascading
• Synchronous clear input
• Fully independent clock circuit
• TTL compatible inputs and outputs

Benefits:

• Simplified system design with synchronous operation
• Improved system performance due to high-speed operation
• Expandable counting range through cascading
• Easy system reset with synchronous clear
• Compatibility with standard TTL logic families

Technical Specifications:

The 74F161DC operates from a 5V power supply. It features a maximum clock frequency dependent on operating conditions and loading. The device has a synchronous clear input that allows the counter to be reset to zero on the next clock pulse. The load input allows for presetting the counter to any desired value. The carry output facilitates cascading multiple counters to achieve higher counting ranges. The device is supplied in a ceramic dual in-line package (CERDIP).

Rochester Electronics provides a reliable source for this part, ensuring continued support for systems requiring the 74F161DC. Their remanufacturing process ensures the devices meet original manufacturer specifications, providing a reliable and high-quality component.
