Description and Introduction

CMOS Digital Integrated Circuit Silicon Monolithic Dual J-K Flip Flop with Preset and Clear The TC74AC109FN is a dual positive-edge-triggered JK flip-flop with preset and clear functions, manufactured by Toshiba.  

### **Specifications:**  
- **Logic Family:** AC Series (Advanced CMOS)  
- **Supply Voltage Range:** 2.0V to 5.5V  
- **High-Speed Operation:** 4.5ns (typical) at 5V  
- **Low Power Consumption:** 4μA (max) at 5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** 16-pin plastic SOP (Small Outline Package)  
- **Input/Output Compatibility:** TTL levels  
- **Trigger Type:** Positive-edge-triggered  
- **Features:**  
  - Dual JK flip-flops with independent J, K, clock, preset, and clear inputs  
  - Direct clear and preset for asynchronous control  
  - Balanced propagation delays  

### **Descriptions and Features:**  
- The TC74AC109FN integrates two JK flip-flops in a single package, each with individual control inputs.  
- It operates with a wide voltage range, making it suitable for both 3.3V and 5V systems.  
- The positive-edge-triggered design ensures reliable state changes synchronized with the clock signal.  
- Asynchronous preset and clear functions allow immediate output control regardless of the clock state.  
- The AC series provides high-speed performance while maintaining low power consumption.  
- Suitable for applications requiring sequential logic, such as counters, registers, and state machines.  

This information is based solely on the manufacturer's datasheet and technical documentation.
