Description and Introduction

4-Bit Synchronous Binary Counters The SN74HC161N 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  
- **High-Level Output Current:** -5.2mA  
- **Low-Level Output Current:** 5.2mA  
- **Propagation Delay Time:** 24ns (typical at 5V)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** PDIP-16 (Plastic Dual In-Line Package)  

### **Descriptions:**  
The SN74HC161N is a high-speed CMOS logic counter with synchronous reset functionality. It features parallel load capability, allowing preset data to be loaded into the counter. The device operates synchronously with the clock signal, ensuring reliable counting.  

### **Features:**  
- **Synchronous Counting:** All flip-flops are clocked simultaneously.  
- **Parallel Load Capability:** Allows loading of preset values.  
- **Asynchronous Master Reset:** Clears all outputs independently of the clock.  
- **Carry Output:** Enables cascading of multiple counters.  
- **Wide Operating Voltage:** Supports 2V to 6V operation.  
- **Low Power Consumption:** Typical ICC of 4μA (at 5V).  
- **High Noise Immunity:** CMOS technology ensures robust performance.  

This information is based on the manufacturer's datasheet. For detailed electrical characteristics and timing diagrams, refer to TI's official documentation.
