Description and Introduction

4-Bit Synchronous Binary Counters The SN74HC161D is a 4-bit synchronous binary counter manufactured by Texas Instruments (TI). Below are the factual details from Ic-phoenix technical data files:  

### **Manufacturer:**  
Texas Instruments (TI)  

### **Pb-Free Specifications:**  
- The SN74HC161D is **Pb-free (RoHS compliant)**.  
- It complies with the Restriction of Hazardous Substances (RoHS) directive.  

### **Descriptions:**  
- **Type:** 4-bit synchronous binary counter  
- **Operating Voltage:** 2V to 6V (HC family)  
- **Logic Family:** HC (High-Speed CMOS)  
- **Package Type:** SOIC-16  
- **Counting Mode:** Synchronous (parallel load capability)  
- **Reset Function:** Asynchronous master reset (clear)  

### **Features:**  
- **Synchronous Operation:** Clocked counting with parallel load capability.  
- **Asynchronous Clear:** Reset function independent of the clock.  
- **Parallel Load:** Allows presetting the counter to any value.  
- **Carry Output:** Enables cascading of multiple counters.  
- **High-Speed CMOS:** Low power consumption with high noise immunity.  
- **Wide Operating Voltage:** 2V to 6V.  
- **Output Drive Capability:** Standard CMOS output levels.  

This information is strictly based on the manufacturer's specifications.

Application Scenarios & Design Considerations

4-Bit Synchronous Binary Counters

Alternative Part Number

  • CD74HC161E --: Same 4-bit synchronous binary counter function with identical HC logic family and pinout, available in PDIP package as a direct functional substitute.
  • MC74HC161ADG --: Pin-compatible 4-bit synchronous counter in the 74HC family with equivalent logic behavior, Pb-free SOIC package, from a well-established alternate source.
  • 74HC161D,653 --: Standard 74HC161 synchronous binary counter in SO16 package, functionally and pin-compatible with the original, Pb-free and widely available.
  • 74HC161D --: Standard 74HC161 synchronous counter in SOIC package, same logic function and pinout from an alternate supplier.
