Description and Introduction

Dual J-K Positive-Edge-Triggered Flip-Flops With Clear And Preset The SNJ54ALS109AJ is a dual positive-edge-triggered J-K flip-flop manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Technology:** Advanced Low-Power Schottky (ALS)  
- **Supply Voltage Range:** 4.5V to 5.5V  
- **Operating Temperature Range:** -55°C to +125°C (Military Grade)  
- **Propagation Delay (Typical):** 12 ns  
- **Power Dissipation (Typical):** 45 mW  
- **Input Current (Max):** ±1 mA  
- **Output Current (High/Low):** ±2.6 mA / ±24 mA  
- **Package Type:** Ceramic Dual-In-Line (CDIP)  

### **Descriptions:**
- The SNJ54ALS109AJ is a dual J-K flip-flop with individual J, K, clock (CLK), preset (PRE), and clear (CLR) inputs.  
- Each flip-flop is positive-edge-triggered, meaning the output changes state on the rising edge of the clock signal.  
- It features asynchronous preset and clear inputs for direct control over the output state.  

### **Features:**
- **Dual Flip-Flop:** Contains two independent J-K flip-flops in a single package.  
- **Edge-Triggered Clocking:** Responds to the positive clock transition.  
- **Asynchronous Controls:** Preset (PRE) and clear (CLR) override clock and data inputs.  
- **High Noise Immunity:** ALS technology provides improved noise margins.  
- **Wide Operating Temperature:** Suitable for military and harsh environments.  
- **Schottky-Clamped:** Ensures high-speed performance.  

This device is designed for high-reliability applications, including aerospace and defense systems.
