Functional Features

The CD74HCT109EG4 is a high-speed CMOS integrated circuit that consists of two J-K flip-flops with set and reset functionality. It operates within a wide supply voltage range of 2V to 6V, making it suitable for various digital logic applications. The flip-flops can be triggered by an external clock signal, and their outputs can be set or reset using the preset and clear inputs, respectively.

Advantages and Disadvantages

Advantages: - High-speed operation - Wide supply voltage range - Dual flip-flop design with set and reset functionality - Compact SOIC package for space-saving integration

Disadvantages: - Limited maximum operating frequency compared to some other ICs - Requires external clock signal for proper operation

Working Principles

The CD74HCT109EG4 utilizes CMOS technology to implement the dual J-K flip-flops. When the clock input (CLK) receives a rising edge, the current state of the flip-flops is transferred to their respective outputs. The preset (PR) and clear (CLR) inputs allow for setting and resetting the flip-flops, respectively. The complementary outputs (Q1', Q2') provide inverted versions of the main outputs (Q1, Q2).

Detailed Application Field Plans

The CD74HCT109EG4 is commonly used in various digital systems and applications, including but not limited to: - Counters and dividers - Frequency synthesizers - State machines - Data storage and retrieval systems - Control circuits
