Description and Introduction

Synchronous 4-Bit Binary Counters The SN54HC163J is a 4-bit synchronous binary counter manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** Synchronous Binary Counter  
- **Number of Bits:** 4  
- **Supply Voltage Range:** 2V to 6V  
- **Operating Temperature Range:** -55°C to +125°C (Military grade)  
- **Package Type:** CDIP (Ceramic Dual In-Line Package)  
- **Mounting Type:** Through-Hole  
- **Clock Frequency:** Up to 25 MHz (typical at 5V)  
- **Output Type:** Standard  
- **Features Synchronous Counting:** All flip-flops are clocked simultaneously  
- **Reset Capability:** Synchronous reset (clear)  
- **Parallel Load Capability:** Allows presetting the counter  

### **Descriptions:**  
The SN54HC163J is a high-speed CMOS logic 4-bit synchronous counter with an internal carry look-ahead for cascading. It features synchronous operation, meaning the outputs change only on the rising edge of the clock pulse. The counter can be synchronously cleared or loaded with a parallel input value.  

### **Features:**  
- **Synchronous Counting:** All state changes occur on the clock edge.  
- **Parallel Load Inputs:** Allows loading a preset value.  
- **Synchronous Reset (Clear):** Resets the counter to zero on the clock edge when enabled.  
- **Carry Look-Ahead:** Simplifies cascading multiple counters.  
- **Wide Operating Voltage Range:** 2V to 6V.  
- **High Noise Immunity:** Typical of CMOS technology.  
- **Low Power Consumption:** Suitable for battery-operated applications.  

This part is designed for military and high-reliability applications due to its extended temperature range and ceramic packaging.

Application Scenarios & Design Considerations

Synchronous 4-Bit Binary Counters

Alternative Part Number

  • CD74HC163E --: Same 4-bit synchronous binary counter function in the HC logic family, available in a comparable through-hole package, and directly interchangeable in most designs.
  • MC74HC163ADG --: Pin-compatible HC-series 4-bit synchronous counter with equivalent logic function and similar electrical characteristics, offering a second-source option.
  • 74HC163N --: Standard HC-family 4-bit synchronous binary counter in DIP package, functionally equivalent and widely available as a cost-effective alternative.
