Description
The HI-359x family from Holt Integrated Circuits are silicon gate CMOS ICs for interfacing up to eight ARINC 429 receive buses to a high-speed Serial Peripheral Interface (SPI) enabled microcontroller.
Features
- include the ability to switch the bit-signifiance of the ARINC 429 label and to recognize the 32nd received ARINC bit as either data or a parity flag. Some versions provide a digital transmit channel which can be utilized with an external line driver such as HI-8570 to relay information from multiple sources, for example sensors, to a single collection point such as a flight com.
