Description and Introduction

3 TO 8 LINE DECODER (INVERTING) The M74HC138M1R is a high-speed CMOS decoder/demultiplexer manufactured by STMicroelectronics (ST). Below are the factual details from Ic-phoenix technical data files:

### **Manufacturer:**  
STMicroelectronics (ST)  

### **Specifications:**  
- **Logic Type:** Decoder/Demultiplexer  
- **Technology:** High-Speed CMOS (HC)  
- **Number of Input Lines:** 3 (A0, A1, A2)  
- **Number of Output Lines:** 8 (Y0-Y7)  
- **Supply Voltage Range:** 2V to 6V  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package Type:** SO-16  
- **Propagation Delay:** Typically 17 ns at 5V  
- **Low Power Consumption:**  
  - 4µA max (static current)  
  - 80µA max (dynamic current at 5V)  
- **Compliance:**  
  - ESD Protection: HBM > 2000V, MM > 200V  
  - Latch-up immunity > 300mA  

### **Descriptions:**  
The M74HC138M1R is a 3-to-8 line decoder/demultiplexer that accepts three binary weighted inputs (A0, A1, A2) and provides eight mutually exclusive active-low outputs (Y0-Y7). It features three enable inputs (two active-low and one active-high) to simplify cascading and chip selection.  

### **Features:**  
- **High Noise Immunity:** Typical CMOS noise margin of 30% of VCC  
- **Wide Operating Voltage Range:** 2V to 6V  
- **Low Power Dissipation:** Suitable for battery-operated devices  
- **Balanced Propagation Delays:** Ensures reliable performance  
- **Multiple Enable Inputs:** Allows easy expansion (E1, E2, E3)  
- **Schmitt Trigger Action on Inputs:** Improves noise rejection  

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

Application Scenarios & Design Considerations

3 TO 8 LINE DECODER (INVERTING)

Alternative Part Number

  • SN74HC138N --: Pin-compatible 3-to-8 line decoder/demultiplexer in the same 74HC logic family, widely available and functionally equivalent.
  • CD74HC138E --: Direct functional equivalent 3-to-8 decoder with matching HC logic levels and pinout, suitable drop-in replacement.
  • MC74HC138AN --: Same 3-to-8 decoder function in 74HC series with compatible pinout and electrical characteristics.
  • SN74HC138DR --: Same 3-to-8 line decoder/demultiplexer function in the 74HC logic family with identical pinout and SOIC package, widely available and directly drop-in compatible.
  • MC74HC138ADG --: Alternative 74HC138 3-to-8 decoder from another major vendor with matching logic function and pinout, offering supply-chain redundancy.
