Description and Introduction

DUAL D-TYPE POSITIVE EDGE-TRIGGERED FLIP-FLOP The SN74LS74N is a dual D-type positive-edge-triggered flip-flop manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Family:** LS (Low-Power Schottky)  
- **Number of Circuits:** 2 (Dual Flip-Flop)  
- **Trigger Type:** Positive Edge  
- **Supply Voltage (VCC):** 4.75V to 5.25V  
- **High-Level Input Voltage (VIH):** 2V (min)  
- **Low-Level Input Voltage (VIL):** 0.8V (max)  
- **High-Level Output Voltage (VOH):** 2.7V (min) at IOH = -0.4mA  
- **Low-Level Output Voltage (VOL):** 0.5V (max) at IOL = 8mA  
- **Propagation Delay Time (tPLH/tPHL):** 20ns (typ) at VCC = 5V, CL = 15pF  
- **Operating Temperature Range:** 0°C to 70°C  
- **Package Type:** PDIP-14 (Plastic Dual In-Line Package)  

### **Descriptions and Features:**  
- Each flip-flop has individual **Data (D), Clock (CLK), Set (PRE), and Clear (CLR) inputs**.  
- **Asynchronous Set (PRE) and Clear (CLR) inputs** override the clock.  
- **Direct Set and Clear** ensure independent control of the outputs.  
- **Positive-edge-triggered** clocking ensures stable operation.  
- **Wide operating voltage range** (4.75V to 5.25V).  
- **Low power consumption** (typical 10mW per flip-flop).  
- **TTL-compatible inputs and outputs**.  
- **Applications:** Data storage, registers, counters, and control logic.  

This information is strictly based on the manufacturer's datasheet for the SN74LS74N.
