Description and Introduction

4 BIT SYNCHRONOUS UP/DOWN COUNTERS The M74HC190M1R is a high-speed CMOS 4-bit synchronous up/down counter manufactured by STMicroelectronics.  

### **Specifications:**  
- **Logic Family:** HC  
- **Technology:** CMOS  
- **Supply Voltage Range:** 2V to 6V  
- **Operating Temperature Range:** -55°C to +125°C  
- **Package:** SO-16  
- **Counting Mode:** Synchronous Up/Down  
- **Number of Bits:** 4  
- **Clock Frequency:** Typically 50 MHz at 5V  
- **Propagation Delay:** 14 ns (typical at 5V)  
- **Input Capacitance:** 3.5 pF (typical)  
- **Output Current:** ±5.2 mA  

### **Descriptions:**  
The M74HC190M1R is a presettable synchronous up/down counter with parallel load capability. It features a ripple clock output (RCO) for cascading multiple counters and operates synchronously with the clock signal.  

### **Features:**  
- Synchronous counting  
- Parallel load for preset values  
- Up/Down counting mode selection  
- Ripple Clock Output (RCO) for cascading  
- Low power consumption  
- High noise immunity  
- Balanced propagation delays  

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