Description and Introduction

Octal Buffers/Drivers With 3-State Outputs The SN74LV244APWR is an octal buffer and line driver manufactured by Texas Instruments (TI)/Burr-Brown (BB).  

### **Specifications:**  
- **Logic Type:** Buffer/Line Driver  
- **Number of Channels:** 8  
- **Output Type:** 3-State  
- **Voltage Supply Range:** 2V to 5.5V  
- **High-Level Output Current:** -12mA  
- **Low-Level Output Current:** 12mA  
- **Propagation Delay Time:** 7.5ns (max) at 5V  
- **Operating Temperature Range:** -40°C to 85°C  
- **Package:** TSSOP-20  

### **Descriptions:**  
The SN74LV244APWR is designed for 2V to 5.5V VCC operation and features non-inverting outputs. It is used for signal buffering and driving high-capacitance loads.  

### **Features:**  
- Supports mixed-mode voltage operation  
- 3-State outputs for bus-oriented applications  
- Typical output skew < 1ns  
- Low power consumption (ICC = 20µA max)  
- Inputs accept voltages up to 5.5V  
- Ioff supports partial-power-down mode  

This device is commonly used in digital systems for signal isolation and bus driving.

Application Scenarios & Design Considerations

Octal Buffers/Drivers With 3-State Outputs

Alternative Part Number

  • MC74LCX244DTG --: Octal buffer/line driver with 3-state outputs in the same LV/LVC logic family and TSSOP package, pin-compatible and widely available as a direct functional replacement.
  • 74LVC244APW,118 --: Octal buffer/line driver with 3-state outputs, 2.0-3.6V operation, TSSOP-20 package; functionally equivalent to the SN74LV244A with comparable drive and speed.
  • SN74LVC244APWR --: Same manufacturer's LVC-family octal buffer in TSSOP-20; similar function and pinout, though it operates at a slightly lower voltage range and is a different series from the LV part.
