Description and Introduction

Dual D-type pos.-edge-triggered flip-flops with preset and clear The SN74LS74ADR is a dual D-type positive-edge-triggered flip-flop manufactured by Texas Instruments (TI). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Texas Instruments (TI)  
- **Technology Family:** LS (Low-Power Schottky)  
- **Number of Circuits:** 2 (Dual Flip-Flop)  
- **Logic Type:** D-Type Flip-Flop  
- **Trigger Type:** Positive Edge  
- **Supply Voltage Range:** 4.75V to 5.25V (Nominal 5V)  
- **High-Level Output Current:** -0.4mA  
- **Low-Level Output Current:** 8mA  
- **Propagation Delay Time (Max):** 40ns (CLK to Q)  
- **Operating Temperature Range:** 0°C to 70°C  
- **Package / Case:** SOIC-14  
- **Mounting Type:** Surface Mount  

### **Descriptions:**  
- The SN74LS74ADR contains two independent D-type flip-flops with individual clear (CLR) and preset (PRE) inputs.  
- Data is transferred to the output (Q) on the positive edge of the clock (CLK) pulse.  
- Asynchronous clear and preset inputs override the clock and data inputs.  

### **Features:**  
- **Dual Flip-Flop:** Two independent flip-flops in a single package.  
- **Edge-Triggered Clocking:** Ensures stable data transfer on the rising clock edge.  
- **Asynchronous Clear and Preset:** Allows immediate reset or set of outputs.  
- **Wide Operating Voltage:** Optimized for 5V systems.  
- **Low Power Consumption:** LS technology reduces power usage compared to standard TTL.  
- **High Noise Immunity:** Schottky-clamped inputs improve noise resistance.  

This information is based solely on the manufacturer's datasheet and product documentation.
