Description and Introduction

Quadruple Bus Transceivers The SNJ54LS243W is a quadruple bus transceiver manufactured by Texas Instruments (TI). Here are the specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Specifications:**  
- **Manufacturer:** Texas Instruments (TI)  
- **Part Number:** SNJ54LS243W  
- **Technology:** LS (Low-Power Schottky)  
- **Package:** Ceramic Flatpack (W)  
- **Operating Temperature Range:** -55°C to +125°C (Military-grade)  
- **Supply Voltage (VCC):** 4.5V to 5.5V  
- **Logic Family:** TTL (Transistor-Transistor Logic)  
- **Number of Channels:** 4 (Quadruple)  
- **Data Rate:** Standard TTL speeds  
- **Output Type:** 3-State  

### **Description:**  
The SNJ54LS243W is a military-grade, quadruple bus transceiver designed for bidirectional data communication between buses. It features 3-state outputs for bus-oriented applications and is built using low-power Schottky technology for improved speed and power efficiency.  

### **Features:**  
- **Bidirectional Data Flow:** Allows data transmission in both directions.  
- **3-State Outputs:** Supports bus sharing and reduces loading effects.  
- **Military Temperature Range:** Operates reliably in harsh environments (-55°C to +125°C).  
- **Low Power Consumption:** LS technology ensures reduced power dissipation.  
- **High Noise Immunity:** TTL-compatible inputs with improved noise margins.  
- **Ceramic Flatpack Package:** Robust packaging for military and aerospace applications.  

This information is strictly factual and based on the provided knowledge base.

Application Scenarios & Design Considerations

Quadruple Bus Transceivers

Alternative Part Number

  • 74LS243N --: Same 4-bit bus transceiver function in a standard DIP package; widely available and pin-compatible in function, suitable for through-hole designs.
  • DM74LS243N --: Second-source LS243 quad bus transceiver with equivalent logic and drive characteristics, offering supply-chain flexibility.
  • SN74LS243N --: Commercial-grade version of the same LS243 transceiver family, electrically equivalent for non-military temperature applications.
