Key Featrues
High Common Mode Transient Immunity (CMTI) of 25kV/µs: This feature ensures robust performance in environments with high electrical noise, making the isolator suitable for industrial applications where electromagnetic interference (EMI) is prevalent. The high CMTI enhances reliability and reduces the risk of data corruption in noisy conditions.
Capacitive Coupling Technology: The use of capacitive coupling for isolation provides high-speed data transmission (up to 150Mbps) with low power consumption. This technology is ideal for applications requiring fast and efficient signal isolation, such as in communication systems and high-speed data acquisition.
Wide Operating Voltage Range (2.7V to 5.5V): This flexibility allows the isolator to be used in a variety of electronic systems, from low-power devices to standard 5V systems. It simplifies design integration and broadens the range of potential applications, including battery-powered devices and mixed-voltage systems.
High Isolation Voltage (4243Vrms): The high isolation voltage ensures safe operation in applications where electrical isolation is critical, such as in medical devices, industrial control systems, and power supplies. This feature protects sensitive components and ensures user safety by preventing high-voltage transients from crossing the isolation barrier.
Compact 16-SOIC Package: The small form factor and surface-mount design make the isolator suitable for space-constrained applications. The 16-SOIC package is easy to integrate into PCB designs, enabling high-density layouts and reducing the overall footprint of the system. This is particularly beneficial in portable and miniaturized electronic devices.
