Description and Introduction

3 TO 8 LINE DECODER/LATCH (INVERTING) The M74HC137M1R is a high-speed CMOS 3-to-8 line decoder/demultiplexer with address latches, manufactured by STMicroelectronics (ST).  

### **Key Specifications:**  
- **Logic Family:** HC (High-Speed CMOS)  
- **Supply Voltage Range:** 2V to 6V  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SO-16  
- **Number of Inputs:** 3 (Address lines)  
- **Number of Outputs:** 8 (Active LOW)  
- **Propagation Delay:** Typically 17 ns at 5V  
- **Low Power Consumption:** CMOS technology ensures low static and dynamic power dissipation.  

### **Descriptions and Features:**  
- **3-to-8 Line Decoder/Demultiplexer:** Converts a 3-bit binary input into one of eight mutually exclusive outputs.  
- **Address Latches:** Includes built-in latches to hold the input address, enabling stable output selection.  
- **Active LOW Outputs:** The selected output is driven LOW while all others remain HIGH.  
- **Enable Inputs:** Features two enable inputs (E1 and E2) and an active HIGH enable (E3) for flexible control.  
- **High Noise Immunity:** CMOS technology provides robust noise resistance.  
- **Wide Operating Voltage:** Supports 2V to 6V, making it compatible with TTL levels.  
- **Applications:** Used in memory addressing, data routing, and logic function generation.  

This device is suitable for industrial, automotive, and consumer electronics applications requiring reliable decoding functionality.
