NewsMarch 06, 2026
Aliso Viejo, Calif. Holt Integrated Circuits announced the release of its ADK-85104 evaluation board, a small ready-to-use platform intended to help engineers rapidly evaluate and characterize Holt’s HI-85104 fault-isolated quad ARINC 429 line driver.
According to the company announcement, the HI-85104 enables integrated 37.5 Ohm impedance-matched outputs with on-chip fuses, will output tristate capability when powered up or down, and provides optional zero-Ohm AMP outputs for external lightning protection networks.
The evaluation board for the part is powered by a 3.3 V VDD supply and can support a digital input range of 1.8 V to 5 V, which allows direct interface with a variety of FPGAs and microcontrollers without the need for additional level shifting.
