Description and Introduction

4 TO 16 LINE DECODER/LATCH The M74HC4514M1R is a 4-to-16 line decoder/demultiplexer with latched inputs, manufactured by STMicroelectronics (ST).  

### **Specifications:**  
- **Logic Type:** CMOS  
- **Supply Voltage Range:** 2V to 6V  
- **High Noise Immunity:** Typical CMOS level  
- **Low Power Consumption:** Suitable for battery-operated devices  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package Type:** SO-24  
- **Input Type:** Schmitt Trigger (for noise immunity)  
- **Output Type:** Standard  
- **Propagation Delay:** Typically 17ns at 5V  

### **Descriptions:**  
- The M74HC4514M1R decodes four binary-coded inputs into one of sixteen mutually exclusive outputs.  
- It features latched inputs, meaning the input data is stored when the latch enable (LE) is high.  
- The output enable (OE) pin allows outputs to be disabled (high impedance).  

### **Features:**  
- **4-to-16 Line Decoding:** Converts 4-bit binary input to a single active-low output.  
- **Latch Function:** Inputs are stored when LE is high.  
- **Output Enable (OE):** Disables all outputs when low.  
- **Wide Operating Voltage:** 2V to 6V.  
- **High-Speed Operation:** Suitable for high-performance applications.  
- **Low Power Consumption:** Ideal for portable and battery-powered devices.  
- **Schmitt Trigger Inputs:** Improved noise rejection.  

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

Application Scenarios & Design Considerations

4 TO 16 LINE DECODER/LATCH

Alternative Part Number

  • CD74HC4514M --: Same 4-to-16 line decoder/demultiplexer function in the HC logic family, SOIC package, direct functional equivalent with different naming.
  • MC74HC4514ADWR2 --: HC-series 4-to-16 decoder/latch with identical logic function and pinout, available in SOIC wide-body package.
  • 74HC4514D --: Standard 74HC4514 4-to-16 line decoder in SOIC-24, same function and supply range, different manufacturer series prefix.
  • MC74HC4514ADWR2G --: Equivalent HC-series 4-to-16 decoder/demultiplexer with latch, same logic function and pinout, good second-source option with strong availability.
