Description and Introduction

Dual 4-Bit D-Type Edge-Triggered Flip-Flops With 3-State Outputs The SN74ALS874B is a 16-bit D-type edge-triggered flip-flop with 3-state outputs, manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** D-Type Flip-Flop  
- **Number of Bits:** 16  
- **Output Type:** 3-State  
- **Trigger Type:** Positive Edge  
- **Supply Voltage (VCC):** 4.5V to 5.5V  
- **Operating Temperature Range:** 0°C to 70°C  
- **Package Type:** 56-Pin SSOP (Shrink Small Outline Package)  
- **Propagation Delay:** Typically 12ns (max 20ns) at 5V  
- **Output Current (High/Low):** ±15mA  

### **Descriptions:**  
The SN74ALS874B is designed for high-speed digital applications requiring 16-bit data storage. It features edge-triggered flip-flops with buffered clock and output enable controls, allowing for synchronous operation. The 3-state outputs facilitate bus-oriented systems by enabling high-impedance states when not in use.  

### **Features:**  
- **16-bit parallel storage register**  
- **Buffered clock and output enable inputs**  
- **3-state outputs for bus interfacing**  
- **High-speed operation (12ns typical propagation delay)**  
- **Wide operating voltage range (4.5V to 5.5V)**  
- **Compatible with TTL inputs and outputs**  
- **Low power consumption (ALS technology)**  

This device is commonly used in data storage, buffering, and bus interface applications.
