Description and Introduction

Dual J-K Positive-Edge-Triggered Flip-Flops With Clear And Preset The SN74AS109AN is a dual positive-edge-triggered J-K flip-flop manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** J-K Flip-flop  
- **Number of Circuits:** 2  
- **Trigger Type:** Positive Edge  
- **Supply Voltage Range:** 4.5V to 5.5V  
- **High-Level Output Current:** -15mA  
- **Low-Level Output Current:** 48mA  
- **Propagation Delay Time:** 9ns (max) at 5V  
- **Operating Temperature Range:** 0°C to 70°C  
- **Package / Case:** PDIP-16  

### **Descriptions:**  
- The SN74AS109AN features independent J, K, clock (CLK), preset (PRE), and clear (CLR) inputs for each flip-flop.  
- It operates on a positive-edge clock transition.  
- The outputs (Q and Q̅) change state based on J and K inputs when triggered by the clock.  

### **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 immediate output control regardless of clock state.  
- **Wide Operating Voltage:** Compatible with standard 5V logic systems.  
- **High-Speed Operation:** Low propagation delay for fast switching applications.  

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