Typical Applications
ZZISO-20260819 is suitable for 6 applications: Isolated SPI Communication, Isolated CAN Bus Interface, Isolated UART Link, Isolated Power Converter Feedback, Isolated Sensor Interface, Isolated RS-485 Communication.
Isolated SPI Communication
The ZZISO-20260819 is ideal for isolated SPI communication in motor control and industrial automation. Its 150 Mbps data rate supports high-speed SPI clocks, while the 5 kVrms isolation protects the microcontroller from high-voltage transients. The low propagation delay of 10 ns ensures accurate timing for critical control loops. Place the isolator between the MCU and the SPI peripheral to break ground loops and improve noise immunity. The enable pin can be used to power down the isolator when the SPI bus is idle, reducing system power consumption.
Recommended
Isolated CAN Bus Interface
In automotive and industrial CAN networks, the ZZISO-20260819 provides galvanic isolation between the CAN controller and the physical transceiver. Its high common-mode transient immunity of 100 kV/us prevents data corruption in noisy environments. The 150 Mbps data rate easily handles CAN FD speeds up to 5 Mbps. The device operates over a wide temperature range, ensuring reliable performance in engine compartments. Use the enable pin to shut down the isolator during low-power modes, extending battery life in vehicles.
Recommended
Isolated UART Link
The ZZISO-20260819 is perfect for isolated UART links in industrial sensors and PLCs. Its 150 Mbps data rate far exceeds UART requirements, providing ample headroom for future upgrades. The 5 kVrms isolation protects sensitive electronics from ground potential differences in factory environments. The low quiescent current of 1.5 mA per channel is ideal for power-sensitive field devices. The fail-safe output ensures a known state when the input is unpowered, preventing false triggering. This makes the device reliable for long-distance communication.
Recommended
Isolated Power Converter Feedback
In isolated power converters, the ZZISO-20260819 transmits feedback signals across the isolation barrier. Its high data rate and low propagation delay enable fast response to load changes, improving transient performance. The 5 kVrms isolation ensures safety in high-voltage applications. The device's wide supply voltage range allows direct interfacing with the secondary-side controller. The enable pin can be used to disable the isolator during standby, reducing power consumption. This makes it ideal for efficient power supply designs.
Recommended
Isolated Sensor Interface
The ZZISO-20260819 is well-suited for isolated sensor interfaces in medical and industrial monitoring systems. Its high isolation voltage protects patients and equipment from electrical hazards. The 150 Mbps data rate supports high-resolution sensor data streaming. The low propagation delay ensures real-time data acquisition. The device operates over a wide temperature range, making it suitable for various environments. The fail-safe output provides a known state during power-up, preventing false alarms. This ensures reliable and safe operation.
Recommended
Isolated RS-485 Communication
The ZZISO-20260819 is ideal for isolated RS-485 communication in building automation and industrial networks. Its high data rate supports fast data transfer over long distances. The 5 kVrms isolation prevents ground loops and protects against surges. The high common-mode transient immunity ensures reliable operation in electrically noisy environments. The device's low power consumption is beneficial for bus-powered nodes. The enable pin allows the isolator to be powered down when not in use, saving energy. This makes it a robust solution for industrial communication.

Key Differentiators
- Higher data rate of 150 Mbps (vs ISO7741)
- Lower propagation delay of 10 ns (vs ADuM1401)
- Higher common-mode transient immunity of 100 kV/us (vs ADuM1401)
Design Notes
Place 0.1uF decoupling capacitors close to the VCC1 and VCC2 pins to ensure stable operation. Use a solid ground plane under the device to minimize parasitic inductance. Keep the isolation barrier clear of copper traces to maintain the specified isolation voltage.
Route the input and output traces with controlled impedance if the data rate exceeds 50 Mbps. Keep the traces short and direct to minimize signal degradation. Avoid routing high-speed signals near the isolation barrier to prevent coupling.
The ZZISO-20260819 dissipates minimal power, but ensure adequate copper area for heat dissipation in high-temperature environments. The SOIC-16 package has a thermal resistance of 80 C/W, so consider ambient temperature and airflow in your design.
