The 74HC109N is a high-speed Si-gate CMOS device that is part of the 74HC/HCT family. Manufactured by NXP Semiconductors, this integrated circuit is designed to deliver the functionality of dual JK positive-edge-triggered flip-flops with set and reset capabilities. It is a versatile component commonly used in a wide range of digital applications, including counters, registers, and control circuits.

Key Features

• Dual JK Flip-Flop Configuration: The 74HC109N contains two JK flip-flops with individual inputs for J, K, set (SD), reset (RD), and clock (CP), along with separate Q and Q-bar outputs for each flip-flop.
• Positive-Edge Triggering: Each flip-flop is triggered by a high-to-low transition of the clock pulse, ensuring reliable and predictable output state changes.
• Asynchronous Set and Reset: The direct set and reset inputs are independent of the clock and are activated by a low-level input, providing immediate control over the flip-flop states.
• High-Speed Operation: The device is capable of operating at high speeds, with a typical clock frequency of tens of MHz, making it suitable for high-performance systems.
• Low Power Consumption: Utilizing CMOS technology, the 74HC109N offers a balance between high-speed operation and low power dissipation, ideal for power-sensitive applications.
• Wide Operating Voltage Range: It can operate across a wide voltage range from 2V to 6V, accommodating various logic level requirements and power supplies.
• Compatibility: The outputs are compatible with TTL levels, allowing for easy integration with other TTL components.
• Standard DIP Package: The 74HC109N is available in a 16-pin DIP (Dual In-line Package), facilitating easy insertion into standard breadboards and sockets.
