Description and Introduction

8-Line To 1-Line Data Selector / Multiplexer / Register 20-PDIP 0 to 70 The SN74LS356N is a part of the SN74LS series of integrated circuits manufactured by Texas Instruments.  

### **Specifications:**  
- **Manufacturer:** Texas Instruments  
- **Series:** SN74LS  
- **Logic Family:** LS (Low-Power Schottky)  
- **Function:** 4-Bit Binary Counter (Synchronous)  
- **Package:** PDIP (Plastic Dual In-Line Package)  
- **Pin Count:** 16  
- **Operating Voltage:** 4.75V to 5.25V (Standard 5V TTL)  
- **Operating Temperature Range:** 0°C to 70°C (Commercial)  
- **Propagation Delay:** Typically 15ns (varies with conditions)  
- **Power Consumption:** Low-power Schottky design for reduced power dissipation  

### **Descriptions:**  
The SN74LS356N is a synchronous 4-bit binary counter with parallel load capability. It is designed for high-speed counting applications and features a synchronous reset function. The counter advances on the rising edge of the clock input when enabled.  

### **Features:**  
- **Synchronous Counting:** Clocked operation for precise timing  
- **Parallel Load:** Allows preset data to be loaded into the counter  
- **Synchronous Reset:** Clears the counter on the clock edge  
- **TTL-Compatible Inputs/Outputs:** Works with standard TTL logic levels  
- **High-Speed Operation:** Suitable for fast digital systems  
- **Low Power Consumption:** Benefits from LS (Low-Power Schottky) technology  

This information is based on the manufacturer's datasheet and standard specifications for the SN74LS series.

Application Scenarios & Design Considerations

8-Line To 1-Line Data Selector / Multiplexer / Register 20-PDIP 0 to 70

Alternative Part Number

  • DM74LS356N --: Same 74LS356 function (8-input multiplexer/latch with 3-state outputs) in a DIP package, pin-compatible and electrically equivalent.
  • 74LS356PC --: Equivalent 74LS356 device from a different vendor with the same logic function and DIP pinout, suitable as a direct drop-in replacement.
  • MC74LS356N --: Alternate-source 74LS356 in a standard DIP package, matching the original function and pin configuration for direct substitution.
