Description and Introduction

Quadruple Bus Buffers With 3-State Outputs The SN74LS125ADBR is a quad bus buffer gate manufactured by Texas Instruments. Below are its specifications, descriptions, and features:

### **Specifications:**  
- **Manufacturer:** Texas Instruments  
- **Type:** Quad Bus Buffer Gate  
- **Logic Family:** LS (Low-Power Schottky)  
- **Number of Channels:** 4  
- **Output Type:** 3-State  
- **Supply Voltage Range:** 4.75V to 5.25V  
- **High-Level Output Current:** -2.6mA  
- **Low-Level Output Current:** 24mA  
- **Propagation Delay Time:** 15ns (max)  
- **Operating Temperature Range:** 0°C to 70°C  
- **Package:** SSOP (Shrink Small Outline Package)  
- **Pin Count:** 14  

### **Descriptions:**  
- The SN74LS125ADBR is a quadruple bus buffer gate with 3-state outputs.  
- It is designed for bidirectional bus communication and signal buffering.  
- The 3-state outputs allow multiple devices to share a common bus without interference.  
- It is compatible with TTL (Transistor-Transistor Logic) inputs and outputs.  

### **Features:**  
- **Low Power Consumption:** Typical power dissipation of 10mW per gate.  
- **High-Speed Operation:** Optimized for fast switching applications.  
- **3-State Outputs:** Allows bus-oriented applications.  
- **Wide Operating Voltage Range:** Supports standard 5V logic levels.  
- **Schottky Clamped Inputs:** Improves noise immunity and switching speed.  

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

Application Scenarios & Design Considerations

Quadruple Bus Buffers With 3-State Outputs

Alternative Part Number

  • MC74LS125ADG --: Quad bus buffer with 3-state outputs in the same LS logic family, SOIC-14 package, direct functional equivalent to the SN74LS125A.
  • DM74LS125AMX --: Pin-compatible quad 3-state buffer in LS technology with matching electrical characteristics and SOIC-14 footprint.
  • SN74LS125AN --: Same TI LS125A function in a DIP-14 package, suitable when through-hole mounting is acceptable instead of the SOIC version.
