Description and Introduction

SYNCRONOUS PRESETTABLE 4-BIT BINARY COUNTER, WITH ASYNCHRONOUS CLEAR The M74HC161M1R is a high-speed CMOS 4-bit synchronous binary counter with asynchronous reset, manufactured by STMicroelectronics.  

### **Specifications:**  
- **Logic Family:** HC  
- **Technology:** CMOS  
- **Supply Voltage Range:** 2V to 6V  
- **High Noise Immunity:** Typical of CMOS technology  
- **Low Power Consumption:** Suitable for battery-operated devices  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SO-16  

### **Descriptions:**  
- **Functionality:** Synchronous 4-bit binary counter with parallel load and asynchronous reset.  
- **Counting Mode:** Counts on the rising edge of the clock input when enabled.  
- **Parallel Load Capability:** Allows presetting the counter via parallel data inputs.  
- **Asynchronous Reset:** Clears all flip-flops independently of the clock.  
- **Carry Output:** Provides ripple carry for cascading multiple counters.  

### **Features:**  
- **Synchronous Operation:** Clocked counting for precise timing.  
- **Asynchronous Master Reset:** Immediate counter reset regardless of clock state.  
- **Parallel Load Inputs:** Enables preset values to be loaded.  
- **High-Speed Performance:** Compatible with high-frequency applications.  
- **Wide Operating Voltage:** Supports 2V to 6V operation.  
- **Standard Output Drive:** 4mA at 4.5V supply.  

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