Description and Introduction

Dual J-K Positive-Edge-Triggered Flip-Flops With Clear And Preset The SN54ALS109AJ is a dual J-K positive-edge-triggered flip-flop manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** J-K Flip-Flop  
- **Technology:** Advanced Low-Power Schottky (ALS)  
- **Supply Voltage Range:** 4.5V to 5.5V  
- **Operating Temperature Range:** -55°C to +125°C  
- **Package Type:** Ceramic DIP (CDIP)  
- **Number of Circuits:** 2  
- **Trigger Type:** Positive Edge  
- **Output Type:** Differential  
- **Propagation Delay Time:** Typically 12ns at 5V  
- **High-Level Output Current:** -2.6mA  
- **Low-Level Output Current:** 24mA  

### **Descriptions:**  
- The SN54ALS109AJ features independent J-K inputs, clock (CLK) inputs, preset (PRE), and clear (CLR) controls for each flip-flop.  
- It is designed for high-speed, low-power operation in military and aerospace applications.  
- The device is characterized for operation over the full military temperature range.  

### **Features:**  
- **Dual J-K Flip-Flop:** Two independent flip-flops in a single package.  
- **Positive Edge-Triggered:** Data is transferred on the rising edge of the clock pulse.  
- **Asynchronous Clear and Preset:** Directly sets or resets outputs regardless of clock state.  
- **Wide Operating Voltage Range:** Supports 4.5V to 5.5V operation.  
- **High Noise Immunity:** ALS technology provides improved noise margins.  
- **Robust Packaging:** Ceramic DIP ensures reliability in harsh environments.  

This device is part of TI's SN54ALS series, which is designed for high-reliability applications.
