Description and Introduction

QUAD 3-STATE BUFFERS The SN54LS125J is a quad bus buffer gate manufactured by Texas Instruments (TI). Here are its specifications, descriptions, and features:  

### **Specifications:**  
- **Logic Family:** LS (Low-Power Schottky)  
- **Number of Channels:** 4 (Quad)  
- **Logic Type:** Buffer/Driver, 3-State  
- **Supply Voltage Range (VCC):** 4.75V to 5.25V (for SN54 series)  
- **High-Level Output Current:** -2.6 mA  
- **Low-Level Output Current:** 24 mA  
- **Propagation Delay Time:** 15 ns (typical)  
- **Operating Temperature Range:** -55°C to +125°C (Military grade)  
- **Package Type:** Ceramic DIP (Dual In-Line Package)  
- **Pin Count:** 14  

### **Descriptions:**  
- The SN54LS125J is a high-speed, low-power quad bus buffer with 3-state outputs.  
- Designed for military and industrial applications with extended temperature ranges.  
- Each of the four buffers has an independent output enable (OE) input for bus-oriented applications.  
- The 3-state outputs allow multiple devices to share a common bus without interference.  

### **Features:**  
- **3-State Outputs:** Allows connection to a bus system.  
- **High-Impedance Outputs:** When disabled, outputs present minimal load.  
- **Low Power Consumption:** Typical power dissipation of 36 mW.  
- **Schottky Diode Clamping:** Ensures high-speed performance.  
- **Wide Operating Temperature Range:** Suitable for harsh environments.  
- **Balanced Propagation Delays:** Ensures reliable signal integrity.  

This information is based on the manufacturer's datasheet for the SN54LS125J.

Application Scenarios & Design Considerations

QUAD 3-STATE BUFFERS

Alternative Part Number

  • MC74LS125AN --: Quad bus buffer with 3-state outputs in the same LS TTL logic family, pin-compatible DIP-14 device that directly replaces the SN54LS125J function.
  • DM74LS125AN --: Quad 3-state buffer from the 74LS series with identical logic function and DIP-14 pinout, widely available as a drop-in substitute.
  • SN74LS125AN --: Same TI quad 3-state buffer in commercial temperature grade DIP-14 package, electrically equivalent for most applications where the military temperature range is not required.
