This board allows the customer to evaluate the features of the HI-8598 differential ARINC 429 Line Driver IC. It is designed to provide up to +/- 800V galvanic isolation between the line driver and the logic interface. Internal circuitry protects the logic interface with built-in 4kV ESD protection (HBM).
The HI-8598 is powered from two 3.3V power supplies, one for the logic side and one for the line driver side. Test signals can be applied and monitored using the test points.
