Description and Introduction

DUAL J-K NEGATIVE-EDGE-TRIGGERED FLIP-FLOPS WITH PRESET, COMMON CLEAR, AND COMMON CLOCK The SN54S114J is a dual J-K flip-flop with preset and clear, manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** J-K Flip-Flop  
- **Number of Circuits:** 2  
- **Output Type:** Standard  
- **Supply Voltage Range:** 4.5V to 5.5V  
- **Operating Temperature Range:** -55°C to +125°C  
- **Package / Case:** CDIP-16 (Ceramic Dual In-Line Package)  
- **Mounting Type:** Through Hole  
- **Propagation Delay Time:** 12ns (typical)  
- **High-Level Output Current:** -1mA  
- **Low-Level Output Current:** 16mA  

### **Descriptions and Features:**  
- **Dual J-K Flip-Flop:** Contains two independent J-K flip-flops in a single package.  
- **Preset and Clear Inputs:** Allows asynchronous setting or clearing of the flip-flop outputs.  
- **Edge-Triggered Clocking:** Responds to the rising edge of the clock signal.  
- **Schottky-Clamped:** Improves switching speed and reduces power consumption.  
- **Military-Grade (SN54 Series):** Designed for high-reliability applications in harsh environments.  
- **Wide Operating Temperature Range:** Suitable for aerospace, defense, and industrial applications.  

This device is part of TI's **SN54 series**, which is characterized by its robustness and extended temperature range.
