Description and Introduction

Triple Channel, 2/1, 1Mbps, Digital Isolator 16-SOIC -40 to 125 The ISO7231ADW is a digital isolator manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Isolation Voltage:** 2500 Vrms  
- **Data Rate:** Up to 25 Mbps  
- **Number of Channels:** 3  
- **Channel Configuration:** 2 forward & 1 reverse direction  
- **Supply Voltage (VCC1, VCC2):** 3.3 V, 5 V  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOIC-16 (DW)  

### **Descriptions:**  
The ISO7231ADW is a triple-channel digital isolator that provides galvanic isolation for digital signals. It supports bidirectional communication with two forward and one reverse-direction channel. It is designed for high-speed data transmission while ensuring robust isolation performance.  

### **Features:**  
- High-speed data transmission (up to 25 Mbps)  
- Low propagation delay (11 ns typical)  
- High CMTI (50 kV/µs typical)  
- Fail-safe output options  
- Wide supply voltage range (3.3 V or 5 V)  
- Low power consumption  
- Reinforced isolation per UL 1577, VDE, CSA, and CQC standards  

This device is commonly used in industrial automation, motor control, and medical equipment where signal isolation is critical.

Application Scenarios & Design Considerations

Triple Channel, 2/1, 1Mbps, Digital Isolator 16-SOIC -40 to 125

Alternative Part Number

  • ADUM1301ARWZ --: Triple-channel digital isolator with similar channel configuration and SOIC-16 wide-body package; pin-compatible and widely used as a drop-in replacement for the ISO7231 family.
  • SI8631BB-IS --: Triple-channel digital isolator in SOIC-16 wide-body package with comparable data rate and isolation rating; a common cross-reference for TI ISO72xx isolators.
  • MAX14931EASA+ --: Triple-channel reinforced digital isolator offering similar isolation voltage and channel direction; suitable alternative when the ISO7231ADW is unavailable.

- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOIC-16 (DW)  

### **Descriptions:**  
The ISO7231ADW provides galvanic isolation for digital signals using capacitive isolation technology. It is designed for high-speed communication while maintaining signal integrity across isolation barriers.  

### **Features:**  
- High-speed data transmission (up to 25 Mbps)  
- Low propagation delay  
- High common-mode transient immunity (CMTI)  
- Fail-safe output options  
- Wide supply voltage range (3.3 V or 5 V)  
- Safety certifications: UL, CSA, VDE  
- Low power consumption  

This device is commonly used in industrial automation, motor control, and communication systems requiring signal isolation.

Application Scenarios & Design Considerations

Triple Channel, 2/1, 1Mbps, Digital Isolator 16-SOIC -40 to 125

Alternative Part Number

  • ADUM1301ARWZ --: Triple-channel digital isolator with similar channel configuration and SOIC-16 wide-body package; pin-compatible alternative from a different series and vendor.
  • SI8631BC-B-IS1 --: Triple-channel digital isolator in SOIC-16 package with comparable isolation rating and data rate; different naming series makes it easy to distinguish from the source.
  • MAX14931EASE+ --: Triple-channel digital isolator with similar supply voltage range and SOIC-16 footprint; a viable cross-vendor substitute for the ISO7231ADW.
