Partnumber Manufacturer Quantity Availability
SN74109N TI 75 In Stock

Description and Introduction

DUAL J-K POSITIVE-EDGE-TRIGGERED FLIP-FLOPS WITH PRESET AND CLEAR The SN74109N is a dual J-K positive-edge-triggered flip-flop with preset and clear, manufactured by Texas Instruments (TI).  

### **Key Specifications:**  
- **Logic Type:** J-K Flip-Flop  
- **Number of Circuits:** 2  
- **Trigger Type:** Positive Edge  
- **Supply Voltage Range:** 4.75V to 5.25V (standard 5V operation)  
- **Operating Temperature Range:** 0°C to 70°C  
- **Package / Case:** PDIP-16 (Plastic Dual In-line Package)  
- **Mounting Type:** Through-Hole  

### **Descriptions and Features:**  
- Each flip-flop has independent **J, K, Clock (CLK), Preset (PRE), and Clear (CLR)** inputs.  
- **Positive-edge-triggered clocking** ensures reliable state changes only on the rising edge of the clock signal.  
- **Asynchronous Preset (PRE) and Clear (CLR)** override clock and data inputs for immediate output control.  
- **Complementary outputs (Q and Q̅)** provide both true and inverted logic states.  
- **High noise immunity** due to Schmitt-trigger inputs.  
- **Wide operating voltage range** for compatibility with TTL logic levels.  
- **Typical propagation delay:** 15ns (clock to output).  

This device is commonly used in sequential logic circuits, counters, registers, and control applications.

- **Low-Level Output Current (IOL):** 16mA  
- **Propagation Delay Time (tpd):** 30ns (Typical)  
- **Operating Temperature Range:** 0°C to 70°C  
- **Package / Case:** 16-DIP (Dual In-Line Package)  

### **Descriptions and Features:**  
- **Dual Flip-Flop:** Contains two independent J-K flip-flops in a single IC.  
- **Positive-Edge Triggering:** Changes state on the rising edge of the clock signal.  
- **Preset and Clear Inputs:** Asynchronous preset (PRE) and clear (CLR) for direct control.  
- **J and K Inputs:** Allows toggling, setting, or resetting the output based on input conditions.  
- **Complementary Outputs:** Each flip-flop provides true (Q) and inverted (Q̅) outputs.  
- **TTL-Compatible:** Designed for compatibility with TTL logic levels.  
- **Wide Operating Voltage:** Optimized for 5V operation.  

This device is commonly used in digital systems for data storage, counters, and sequential logic applications.
