Description and Introduction

Octal Buffers/Drivers With 3-State Outputs 20-SOIC -40 to 85 The SN74ABT244ADWRG4 is an octal buffer and line driver manufactured by Texas Instruments (TI)/Burr-Brown (BB).  

### **Specifications:**  
- **Logic Type:** Buffer/Line Driver  
- **Number of Bits:** 8  
- **Output Type:** 3-State  
- **Voltage Supply:** 4.5V to 5.5V  
- **Operating Temperature:** -40°C to +85°C  
- **Package:** SOIC-20 (DW)  
- **Mounting Type:** Surface Mount  
- **High-Level Output Current:** -32mA  
- **Low-Level Output Current:** 64mA  
- **Propagation Delay Time:** 3.4ns (max) at 5V  
- **Input Capacitance:** 4.5pF (typ)  
- **Output Capacitance:** 8pF (typ)  

### **Descriptions:**  
The SN74ABT244ADWRG4 is an octal buffer/driver designed for high-speed, low-power operation. It features 3-state outputs for bus-oriented applications and is compatible with TTL input and output levels.  

### **Features:**  
- **High-Speed Operation:** Optimized for 5V systems  
- **3-State Outputs:** Allows connection to a bus system  
- **TTL-Compatible Inputs:** Ensures compatibility with TTL logic levels  
- **Balanced Propagation Delays:** Improves signal integrity  
- **ESD Protection:** Exceeds 2000V per JESD 22  

This device is commonly used in bus interface, memory address driving, and clock buffering applications.
