Description and Introduction

BCD DECADE COUNTERS/ 4-BIT BINARY COUNTERS The SN74LS161AMR1 is a synchronous 4-bit binary counter manufactured by Texas Instruments.  

### **Specifications:**  
- **Logic Family:** LS (Low-Power Schottky)  
- **Number of Bits:** 4  
- **Counting Sequence:** Binary (0 to 15)  
- **Supply Voltage Range:** 4.75V to 5.25V  
- **Operating Temperature Range:** 0°C to 70°C  
- **Package Type:** SOIC-16  
- **Mounting Type:** Surface Mount  
- **Propagation Delay:** Typically 20ns  
- **Maximum Clock Frequency:** 25MHz  
- **Output Type:** Standard  

### **Descriptions:**  
The SN74LS161AMR1 is a synchronous presettable 4-bit binary counter with asynchronous clear. It features parallel load capability, allowing the counter to be preset to any value. The device operates synchronously, meaning the outputs change on the rising edge of the clock signal when enabled.  

### **Features:**  
- Synchronous counting operation  
- Asynchronous master reset (clear)  
- Parallel load capability  
- Carry output for cascading  
- Fully programmable via control inputs  
- Low power consumption (typical 45mW)  
- TTL-compatible inputs and outputs  

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

Application Scenarios & Design Considerations

BCD DECADE COUNTERS/ 4-BIT BINARY COUNTERS

Alternative Part Number

  • CD74HC161E --: 4-bit synchronous binary counter with similar function, different logic family (HC vs LS) and package, widely available.
  • MC74HC161ADG --: Pin-compatible 4-bit binary counter in HC family, direct functional replacement with different series naming.
  • 74HCT161N --: HCT logic 4-bit synchronous counter, TTL-compatible inputs, suitable drop-in alternative from a different series.
  • 74LS161APC --: Same 4-bit synchronous binary counter function with identical LS TTL logic family and pinout, from a different manufacturer and naming series.
  • DM74LS161AN --: Direct functional equivalent 4-bit synchronous counter in the 74LS family with matching pin configuration and electrical characteristics.
  • SN74LS161AN --: Same counter function and LS logic family from the original brand lineage, differing only in package/packaging naming from the source part.
