Description and Introduction

Dual J-K Positive-Edge-Triggered Flip-Flops With Clear And Preset The SN74F109DR is a dual positive-edge-triggered J-K flip-flop manufactured by Texas Instruments. Below are the specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Texas Instruments  
- **Category:** Flip-Flop  
- **Type:** Dual J-K Flip-Flop  
- **Trigger Type:** Positive Edge  
- **Supply Voltage Range:** 4.5V to 5.5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package / Case:** SOIC-16  
- **Mounting Type:** Surface Mount  
- **Output Type:** Differential  
- **Number of Bits per Element:** 1  
- **Number of Elements:** 2  
- **Propagation Delay Time:** 6.5 ns (typical)  
- **High-Level Output Current:** -3 mA  
- **Low-Level Output Current:** 24 mA  

### **Descriptions:**  
- The SN74F109DR is a dual J-K flip-flop with individual J, K, clock (CLK), preset (PRE), and clear (CLR) inputs.  
- It operates on positive-edge triggering, meaning the outputs change state on the rising edge of the clock pulse.  
- The device features asynchronous clear and preset inputs for immediate output control.  
- Designed for high-speed logic applications, it is compatible with TTL logic levels.  

### **Features:**  
- **Dual Flip-Flop:** Contains two independent J-K flip-flops in a single package.  
- **Edge-Triggered Clocking:** Ensures stable output transitions on the rising clock edge.  
- **Asynchronous Clear and Preset:** Allows direct control over outputs regardless of clock state.  
- **High-Speed Operation:** Low propagation delay for fast logic applications.  
- **Wide Operating Voltage:** Supports standard 5V logic systems.  
- **Surface-Mount Package:** SOIC-16 for compact PCB designs.  

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