The HI-8598 is the world’s first galvanically isolated ARINC 429 line driver, available in a compact 18-pin SOIC plastic package. The device uses a patented capacitive isolation and power regulation to provide 800V galvanic isolation between the analog line driver and the logic interface, ensuring isolation between the ARINC 429 data bus and sensitive digital circuitry. This device is intended for use in safety critical systems, where it is essential to completely isolate any faults on the bus from mission critical electronics, making the HI-8598 a good choice for systems that will ultimately require FAA or EASA DO-254 DAL A certification.
The HI-8598 line driver converts logic signals to ARINC 429 levels (such as when using an FPGA or Holt’s HI-3220 or HI-35860 ARINC 429 protocol ICs). The logic inputs feature built-in 4kV ESD input protection (HBM) as well 3.3V logic level compatibility. 37.5 Ohm or 5 Ohm resistors in series with each ARINC output are available to allow the use of external resistors for lightning protection.
The part is available in Industrial -40oC to +85oC, or Extended, -55oC to +125oC temperature ranges. Optional burn-in is available on the extended temperature range.
