Description and Introduction

4-BIT SYNCHRONOUS BINARY COUNTERS The SN74HC163NSR is a 4-bit synchronous binary counter manufactured by Texas Instruments (TEXAS). Below are its specifications, descriptions, and features:

### **Specifications:**  
- **Logic Type:** Synchronous Binary Counter  
- **Number of Bits:** 4  
- **Supply Voltage Range:** 2V to 6V  
- **High-Level Output Current:** -5.2mA  
- **Low-Level Output Current:** 5.2mA  
- **Propagation Delay Time:** 20ns (typical) at 5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package / Case:** SOIC-16  
- **Mounting Type:** Surface Mount  

### **Descriptions:**  
- The SN74HC163NSR is a synchronous, presettable 4-bit binary counter with synchronous reset.  
- It operates synchronously with the clock signal, ensuring all flip-flops change state simultaneously.  
- Features parallel load capability for preset values.  
- Includes a carry output for cascading multiple counters.  

### **Features:**  
- **Synchronous Counting:** All flip-flops are clocked simultaneously.  
- **Parallel Load:** Allows loading preset data via parallel inputs.  
- **Synchronous Reset:** Clears outputs synchronously with the clock.  
- **Carry Output:** Enables cascading for higher-bit counters.  
- **Wide Operating Voltage:** Supports 2V to 6V operation.  
- **Low Power Consumption:** CMOS technology ensures low power dissipation.  
- **High Noise Immunity:** Standard CMOS noise immunity characteristics.  

This information is based solely on the manufacturer's datasheet.

Application Scenarios & Design Considerations

4-BIT SYNCHRONOUS BINARY COUNTERS

Alternative Part Number

  • MC74HC163ADG --: Same 74HC163 4-bit synchronous binary counter function in a similar SOIC-16 package, widely available and pin-compatible.
  • CD74HC163E --: TI's own 74HC163 counter in a PDIP-16 package, electrically equivalent and useful for through-hole or prototyping builds.
  • 74HC163D,653 --: Standard 74HC163 synchronous counter in SO16, a direct functional equivalent from a different series naming.
  • MC74HC163ADTR2G --: Same 74HC163 4-bit synchronous binary counter function in a similar SOIC package, widely available and pin-compatible with the original.
  • 74HC163D --: Equivalent 74HC163 synchronous 4-bit counter in SO16 package, direct functional replacement with comparable speed and drive.
