DESCRIPTION
The HI-8783, HI-8784, and HI-8785 are system components for interfacing 8 bit parallel data to an ARINC 429 bus. The HI-8783 is a logic device only and requires a separate line driver circuit, such as the HI-3182 or HI-8585. The HI-8784 and HI-8785 combine logic and line driver on one chip. The HI-8784 has an output resistance of 37.5 ohms, and the HI-8785 has an output resistance of 10 ohms to facilitate external lightning protection cicuitry. The technology is analog/digital CMOS.
The HI-8783 is available in a 22 pin DIP format as a second source replacement for the Micrel / California Devices DLS-111BV.
