Description and Introduction

Dual 4-Line To 1-Line Data Selectors/Multiplexers The SN54153J is a dual 4-line to 1-line data selector/multiplexer manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features:

### **Specifications:**
- **Logic Type:** Data Selector/Multiplexer  
- **Number of Channels:** 2 (Dual)  
- **Input Lines per Channel:** 4  
- **Output Lines per Channel:** 1  
- **Supply Voltage Range:** 4.5V to 5.5V  
- **Operating Temperature Range:** -55°C to +125°C  
- **Package Type:** Ceramic DIP (Dual In-line Package)  
- **Propagation Delay (Typical):** 15ns  
- **Input Current (Max):** 1.6mA  
- **Output Current (High/Low):** ±4mA  

### **Descriptions:**
- The SN54153J is a high-speed TTL (Transistor-Transistor Logic) device that selects one of four data inputs per channel based on the select inputs (A and B).  
- It features two independent 4-line to 1-line multiplexers with common select inputs and separate enable inputs for each channel.  
- Designed for military and industrial applications, it operates reliably over a wide temperature range.  

### **Features:**
- **Dual 4:1 Multiplexer Configuration** – Two independent multiplexers in one package.  
- **Common Select Inputs** – Shared select lines (A and B) for both channels.  
- **Separate Enable Inputs** – Each channel has its own active-low enable (G) input.  
- **TTL-Compatible Inputs/Outputs** – Ensures compatibility with standard TTL logic levels.  
- **High-Speed Operation** – Low propagation delay for fast switching.  
- **Wide Operating Temperature Range** – Suitable for harsh environments.  

This device is commonly used in digital systems for data routing, signal gating, and parallel-to-serial conversion.

Application Scenarios & Design Considerations

Dual 4-Line To 1-Line Data Selectors/Multiplexers

Alternative Part Number

  • 74LS153 --: Dual 4-to-1 multiplexer with the same function and pinout as the SN54153, in the commercial 74LS series; widely available and a direct functional replacement.
  • CD74HC153E --: High-speed CMOS dual 4-to-1 multiplexer with equivalent logic function and compatible pinout, offering lower power consumption than the original TTL device.
  • MC14539B --: Dual 4-to-1 data selector/multiplexer with similar functionality and DIP package, suitable as a cross-manufacturer alternative when exact TTL compatibility is not critical.
