Description and Introduction

DUAL JK NEGATIVE EDGE-TRIGGERED FLIP-FLOP The SN74LS112N is a dual negative-edge-triggered J-K flip-flop integrated circuit (IC) manufactured by Texas Instruments.  

### **Specifications:**  
- **Logic Family:** LS (Low-Power Schottky)  
- **Number of Circuits:** 2 (Dual Flip-Flop)  
- **Trigger Type:** Negative Edge  
- **Supply Voltage (Vcc):** 4.75V to 5.25V  
- **High-Level Output Current:** -0.4mA  
- **Low-Level Output Current:** 8mA  
- **Propagation Delay Time:** 20ns (typical)  
- **Operating Temperature Range:** 0°C to +70°C  
- **Package Type:** PDIP-16 (Plastic Dual In-Line Package)  
- **Mounting Type:** Through-Hole  

### **Descriptions:**  
The SN74LS112N consists of two independent J-K flip-flops with individual J, K, clock (CLK), preset (PR), and clear (CLR) inputs. Each flip-flop changes state on the negative-going edge of the clock pulse, depending on the J and K inputs.  

### **Features:**  
- **Dual J-K Flip-Flops:** Two flip-flops in a single IC.  
- **Edge-Triggered Operation:** Responds to the negative transition of the clock signal.  
- **Asynchronous Inputs:** Direct Set (PR) and Clear (CLR) for immediate state control.  
- **Wide Operating Voltage:** Compatible with standard 5V TTL logic.  
- **Low Power Consumption:** LS technology ensures efficient power usage.  
- **Standard Pinout:** 16-pin DIP package for easy integration.  

This IC is commonly used in digital systems for data storage, counters, and sequential logic applications.

Application Scenarios & Design Considerations

DUAL JK NEGATIVE EDGE-TRIGGERED FLIP-FLOP

Alternative Part Number

  • MC74LS112AN --: Same dual J-K negative-edge-triggered flip-flop with preset and clear in a DIP-16 package, directly pin-compatible and functionally equivalent.
  • DM74LS112AN --: Pin-compatible LS-TTL dual J-K flip-flop with identical logic function and DIP-16 pinout, suitable as a direct drop-in replacement.
  • SN74LS112AN --: Same device family from the original manufacturer in a DIP-16 package, offering identical electrical characteristics and pinout.
