Description and Introduction

Dual J-K Negative-Edge-Triggered Flip-Flops With Clear and Preset The SN74ALS112A is a dual negative-edge-triggered J-K flip-flop manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** J-K Flip-flop  
- **Trigger Type:** Negative-edge-triggered  
- **Number of Circuits:** 2  
- **Supply Voltage Range:** 4.5V to 5.5V  
- **Operating Temperature Range:** 0°C to +70°C  
- **Propagation Delay Time (tpd):** Typically 10ns (max 15ns) at 5V  
- **Output Current (High/Low):** -0.4mA / 8mA  
- **Power Dissipation:** 50mW per flip-flop (typical)  
- **Package Options:** 16-pin PDIP, SOIC, CDIP  

### **Descriptions:**  
- Each flip-flop has independent J, K, clock (CLK), preset (PRE), and clear (CLR) inputs.  
- The outputs (Q and Q̅) change state on the falling edge of the clock pulse.  
- Asynchronous preset and clear override the clock and data inputs.  

### **Features:**  
- **High-Speed Operation:** Optimized for fast switching applications.  
- **Low Power Consumption:** ALS technology reduces power usage compared to standard TTL.  
- **Wide Operating Voltage:** Compatible with 5V systems.  
- **Asynchronous Inputs:** Direct set/reset capability (PRE and CLR).  
- **Buffered Outputs:** Improved noise immunity and drive capability.  

This device is commonly used in counters, registers, and control logic circuits.
