Description and Introduction

BCD decade counter/4-bit binary counter The SN54LS163AJ is a synchronous 4-bit binary counter manufactured by Texas Instruments (MOT).  

### **Specifications:**  
- **Logic Family:** LS (Low-Power Schottky)  
- **Function:** Synchronous 4-bit binary counter  
- **Operating Voltage:** 4.75V to 5.25V  
- **Clock Frequency:** Up to 25 MHz (typical)  
- **Count Modes:** Synchronous counting with parallel load  
- **Reset Capability:** Synchronous master reset  
- **Operating Temperature Range:** -55°C to +125°C (military-grade)  
- **Package:** 16-pin CDIP (Ceramic Dual In-line Package)  

### **Descriptions:**  
The SN54LS163AJ is a synchronous, presettable 4-bit binary counter with a synchronous clear. It features parallel load capability for preset values and operates synchronously with the clock input.  

### **Features:**  
- Fully synchronous operation  
- Parallel load for preset values  
- Synchronous clear (reset)  
- Carry output for cascading  
- High-speed operation (LS technology)  
- Military-grade temperature range  

This part is designed for high-reliability applications, including military and aerospace systems.

Application Scenarios & Design Considerations

Alternative Part Number

  • 74LS163AN --: Same 4-bit synchronous binary counter function with synchronous clear, commercial temperature range, widely available and pin-compatible in DIP.
  • CD74HC163E --: High-speed CMOS 4-bit synchronous counter with synchronous reset, functionally equivalent and a good drop-in for many LS163 applications.
  • MC74HC163AN --: CMOS 4-bit synchronous binary counter with synchronous clear, similar logic function and DIP package, suitable as a functional replacement.
