Description and Introduction

3.3-V ABT OCTAL BUFFERS/DRIVERS WITH 3-STATE OUTPUTS The SN74LVTT244 from Texas Instruments (TI) is an octal buffer and line driver with 3-state outputs. Here are its specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Logic Type:** Buffer/Line Driver  
- **Number of Channels:** 8 (Octal)  
- **Output Type:** 3-State  
- **Voltage Supply Range:** **2.7V to 3.6V**  
- **Input Voltage (High Level):** **2V (min)**  
- **Input Voltage (Low Level):** **0.8V (max)**  
- **Output Current (High):** **-12mA**  
- **Output Current (Low):** **12mA**  
- **Propagation Delay (Max):** **5.5ns (at 3.3V, 50pF load)**  
- **Operating Temperature Range:** **-40°C to +85°C**  
- **Package Options:** SOIC, TSSOP, SSOP  

### **Description:**  
The SN74LVTT244 is designed for **3.3V LVTTL** systems and provides high-speed, low-power buffering for bus-oriented applications. It features **separate output-enable (OE) inputs** for each 4-bit section, allowing independent control. The outputs remain in a high-impedance state when disabled.  

### **Features:**  
- **3.3V VCC Operation** (compatible with LVTTL)  
- **Supports Mixed-Mode Signal Operation** (5V inputs tolerated)  
- **Bus Hold on Data Inputs** (eliminates need for external pull-up/pull-down resistors)  
- **Typical Output Skew < 1ns**  
- **ESD Protection Exceeds 2000V per JESD 22**  

This device is commonly used in **memory interfaces, data buses, and general-purpose buffering** in 3.3V systems.
