Description and Introduction

Dual 4-Line To 1-Line Data Selectors/Multiplexers With 3-State Outputs The SNJ54LS253J is a dual 4-input multiplexer manufactured by Texas Instruments (TI). Below are the specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Texas Instruments (TI)  
- **Part Number:** SNJ54LS253J  
- **Technology:** LS (Low-Power Schottky)  
- **Package:** Ceramic DIP (Dual In-line Package)  
- **Operating Temperature Range:** -55°C to +125°C (Military-grade)  
- **Supply Voltage (VCC):** 4.75V to 5.25V  
- **Logic Family:** TTL (Transistor-Transistor Logic)  
- **Number of Channels:** 2 (Dual Multiplexer)  
- **Inputs per Multiplexer:** 4  
- **Output Type:** 3-State  

### **Descriptions:**  
The SNJ54LS253J is a high-reliability, military-grade dual 4-input multiplexer with 3-state outputs. It is designed for applications requiring robust performance in harsh environments. Each multiplexer selects one of four data inputs based on the select lines (S0, S1) and provides a 3-state buffered output.  

### **Features:**  
- **Dual 4-to-1 Multiplexer:** Two independent 4-input multiplexers in a single package.  
- **3-State Outputs:** Allows for bus-oriented applications.  
- **Low Power Consumption:** LS technology ensures reduced power dissipation.  
- **High Noise Immunity:** Typical of TTL logic families.  
- **Military Temperature Range:** Suitable for extreme conditions (-55°C to +125°C).  
- **Schottky Clamped:** Improves switching speed and reduces power consumption.

Application Scenarios & Design Considerations

Dual 4-Line To 1-Line Data Selectors/Multiplexers With 3-State Outputs

Alternative Part Number

  • DM74LS253N --: Same dual 4-input multiplexer function with 3-state outputs in a different logic family prefix, widely available and pin-compatible in function.
  • MC74LS253N --: Equivalent LS253 multiplexer from a different manufacturer and naming series, offering the same dual 4-to-1 multiplexer function.
  • SN74LS253N --: Commercial-grade version of the same LS253 multiplexer function, suitable when the military temperature range of the original is not required.
  • 74LS253 --: Same dual 4-to-1 multiplexer function with 3-state outputs in the commercial temperature range; widely available and pin-compatible in DIP packages.
