Description and Introduction

Dual Positive-Edge-Triggered D-Type Flip-Flops With Preset And Clear The SN74AS74A is a dual positive-edge-triggered D-type flip-flop manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Technology Family:** AS (Advanced Schottky)  
- **Supply Voltage Range:** 4.5V to 5.5V  
- **Operating Temperature Range:** 0°C to 70°C  
- **High-Level Output Current:** -15 mA  
- **Low-Level Output Current:** 48 mA  
- **Propagation Delay Time (Max):** 8 ns (CLK to Q)  
- **Setup Time (Min):** 5 ns  
- **Hold Time (Min):** 0 ns  
- **Power Dissipation (Max):** 200 mW  
- **Package Options:** PDIP, SOIC  

### **Descriptions:**  
- Each flip-flop has individual **Data (D), Clock (CLK), Set (PRE), and Clear (CLR)** inputs.  
- Outputs include **Q** and **complementary Q (Q̅)**.  
- **Positive-edge-triggered** clocking for synchronous operation.  
- Asynchronous **Set (PRE)** and **Clear (CLR)** override clock inputs.  

### **Features:**  
- **High-speed operation** with typical propagation delay of 5 ns.  
- **Low power consumption** compared to standard TTL.  
- **Wide operating voltage range** for 5V systems.  
- **Schottky-clamped** for improved noise immunity.  
- **Buffered inputs** for reduced loading effects.  
- **Direct clear and set inputs** for asynchronous control.
