Description and Introduction

4-Bit Synchronous Binary Counters 16-PDIP -40 to 85 The SN74HC161NE4 is a synchronous 4-bit binary counter manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** Synchronous 4-Bit Binary Counter  
- **Supply Voltage Range:** 2V to 6V  
- **High-Level Output Current:** -5.2mA  
- **Low-Level Output Current:** 5.2mA  
- **Propagation Delay Time:** 25ns (typical) at 5V  
- **Operating Temperature Range:** -40°C to 85°C  
- **Package:** PDIP-16 (Plastic Dual-In-Line Package)  
- **Mounting Type:** Through Hole  

### **Descriptions:**  
- The SN74HC161NE4 is a high-speed CMOS logic counter with synchronous reset and parallel load capabilities.  
- It features a fully synchronous operation, meaning all state changes occur on the rising edge of the clock input.  
- It includes a carry output for cascading multiple counters.  

### **Features:**  
- Synchronous counting and loading  
- Asynchronous master reset  
- Fully programmable via parallel inputs  
- Internal look-ahead for fast counting  
- Buffered clock and reset inputs  
- Low power consumption (typical ICC of 4µA)  
- Balanced propagation delays  

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