Description and Introduction

Quad 3-State Buffers The SN74LS125AMR1 is a quad bus buffer gate manufactured by Motorola (MOT).  

### **Specifications:**  
- **Logic Type:** Buffer/Line Driver, Non-Inverting  
- **Number of Channels:** 4  
- **Output Type:** 3-State  
- **Supply Voltage (VCC):** 4.75V to 5.25V  
- **High-Level Output Current:** -2.6mA  
- **Low-Level Output Current:** 24mA  
- **Propagation Delay Time (Max):** 15ns at 5V  
- **Operating Temperature Range:** 0°C to 70°C  
- **Package / Case:** SOIC-14  

### **Descriptions:**  
The SN74LS125AMR1 is a quadruple bus buffer gate with 3-state outputs. It is designed to drive bus lines or buffer memory address registers. Each of the four buffers has an active-low output enable (OE) input that places the output in a high-impedance state when asserted.  

### **Features:**  
- **3-State Outputs:** Allows connection to a bus-organized system.  
- **High-Impedance Outputs:** Prevents loading effects when disabled.  
- **TTL-Compatible Inputs:** Ensures compatibility with standard TTL logic levels.  
- **Wide Operating Voltage Range:** Supports standard 5V logic systems.  
- **Low Power Consumption:** Typical power dissipation of 32mW.  

This information is based solely on the manufacturer's specifications.

Application Scenarios & Design Considerations

Quad 3-State Buffers

Alternative Part Number

  • DM74LS125AMX --: Same 74LS125 quad bus buffer function with tri-state outputs, widely available and pin-compatible.
  • MC74LS125ADG --: Direct functional equivalent of the 74LS125 quad buffer in SOIC package, good second source.
  • SN74LS125AN --: Same TI LS125 quad bus buffer family in a different package, electrically equivalent for most designs.
  • SN74LS125ADR --: Standard TI 74LS125 quad tri-state buffer in SOIC-14, same logic family and pinout, easy drop-in replacement.
