Featured digital isolators

ISO77xx family of digital isolators

The ISO77xx family of digital isolators provides high-performance signal isolation separated by a capacitive silicon dioxide (SiO2) insulation barrier. Through innovative chip design and layout techniques, electromagnetic compatibility of the ISO77xx family is optimized for system-level ESD, EFT, surge and emissions compliance. This family of devices features:

  • 5-kVrms wide creepage and 3-kVrms narrow creepage package options for both high voltage and compact designs.
  • Single, dual, triple, quad and six channel options for all application configurations, including the industry’s smallest six channel 3-kVrms digital isolator.
  • Up to 1000-V working voltage and 100-kV/µs typical common-mode transient immunity enabling use in high voltage, noisy environments such as grid and motor drive applications.

ISOW78xx family of digital isolators with integrated power

The ISOW78xx family combines reinforced isolation and DC/DC conversion in a single package to provide lowest power loss and highest immunity isolation to help enable more robust, reliable industrial systems. 

  • Integrated isolated power and data up to 100 Mbps, minimizing board space and cost for simplified system design.
  • 80% higher efficiency than other integrated solutions, enabling higher power delivery and longer system lifetime.
  • Lower radiated emissions than competitive integrated devices, improving system signal integrity and providing robust EMC to meet IEC 61000-4-x standards.

ISO121x family of isolated digital input receivers

The ISO121x devices are isolated 24V to 60V digital input receivers that improve on traditional optocoupler designs for high-density I/O modules

  • Integrated current limiting circuitry, programmable input voltage thresholds, and no field-side power enable compact board layout
  •  Interfaces with 9-V to 300-V DC and AC digital input modules in programmable logic controllers (PLCs), motor-control, grid infrastructure, and other industrial applications. 
  • Compliant to IEC 61131-2 Type 1, 2, and 3  characteristics for simple and compact PLC digital input designs
