Description and Introduction

Synchronous 4-Bit Binary Counters Here is the factual information about the part **SNJ54HC161J** from the manufacturer **TEAXS**:

### **Specifications:**
- **Manufacturer:** TEAXS  
- **Part Number:** SNJ54HC161J  
- **Type:** Synchronous 4-Bit Binary Counter  
- **Logic Family:** HC (High-Speed CMOS)  
- **Supply Voltage Range:** 2V to 6V  
- **Operating Temperature Range:** -55°C to +125°C  
- **Package Type:** Ceramic DIP (Dual Inline Package)  
- **Number of Pins:** 16  
- **Counting Sequence:** Binary (0000 to 1111)  
- **Clock Frequency:** Up to 25 MHz (typical at 5V)  
- **Output Type:** Standard (Push-Pull)  
- **Reset Function:** Asynchronous Master Reset (MR)  
- **Load Function:** Synchronous Parallel Load  

### **Descriptions:**
The **SNJ54HC161J** is a high-speed CMOS synchronous 4-bit binary counter with an asynchronous master reset. It operates within a wide voltage range (2V to 6V) and is designed for military and aerospace applications due to its extended temperature range (-55°C to +125°C). The counter features parallel load capability, allowing preset values to be loaded synchronously. It also includes a carry output for cascading multiple counters.

### **Features:**
- **Synchronous Counting:** Operates in sync with the clock signal.  
- **Asynchronous Reset:** Immediate reset via the Master Reset (MR) pin.  
- **Parallel Load Capability:** Loads data synchronously when enabled.  
- **Carry Output:** Facilitates cascading of multiple counters.  
- **Wide Operating Voltage:** Supports 2V to 6V operation.  
- **High Noise Immunity:** CMOS technology ensures robust performance.  
- **Military-Grade Reliability:** Designed for harsh environments.  
- **Low Power Consumption:** Efficient power usage typical of HC logic.  

This information is based on the manufacturer's datasheet and technical documentation.
