Description and Introduction

SYNCHRONOUS UP/DOWN DECADE COUNTER The M74HC193M1R is a high-speed CMOS 4-bit synchronous up/down binary counter manufactured by STMicroelectronics (ST).  

### **Specifications:**  
- **Logic Family:** HC (High-Speed CMOS)  
- **Supply Voltage Range:** 2V to 6V  
- **Operating Temperature Range:** -55°C to +125°C  
- **Package:** SO-16  
- **Counting Modes:** Up and Down  
- **Synchronous Operation:** All flip-flops are clocked simultaneously  
- **Asynchronous Features:** Parallel load, master reset  
- **High Noise Immunity:** Standard CMOS levels  
- **Low Power Consumption:** Typical 4µA (at 5V)  

### **Descriptions:**  
- The M74HC193M1R is a 4-bit synchronous up/down counter with separate up/down clock inputs.  
- It features asynchronous parallel load and reset functionality.  
- The counter can be cascaded for higher-bit applications.  

### **Features:**  
- **Synchronous Counting:** Controlled by separate up/down clock inputs  
- **Parallel Load Capability:** Allows presetting the counter value  
- **Asynchronous Master Reset:** Clears all flip-flops independently of the clock  
- **Carry and Borrow Outputs:** Facilitates cascading multiple counters  
- **Wide Operating Voltage:** Compatible with TTL and CMOS levels  
- **High-Speed Operation:** Suitable for high-frequency applications  

This information is based on the manufacturer's datasheet. For detailed specifications, refer to STMicroelectronics' official documentation.
