- Fast switching speed for high-frequency applications
- Low power consumption
- Wide operating temperature range
- Input compatibility with TTL and CMOS logic levels
Technical Specifications:
- Package Type: 6-pin DIP
- Isolation Voltage: Typically 5000Vrms (refer to datasheet for exact value)
- Current Transfer Ratio (CTR): Varies depending on model (refer to datasheet)
- Response Time: Typically in the microsecond range (refer to datasheet)
- Operating Temperature Range: Refer to datasheet (typically -40°C to +85°C)
Applications:
- Signal isolation between control and power circuits
