The HI-8783, HI-8784, and HI-8785 are system components for interfacing 8 bit parallel data to an ARINC 429 bus. TheHI-8783isalogic deviceonly andrequiresaseparate line driver circuit, such as the HI-8382 or HI-8585.

The HI-8783, 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 technologyisanalog/digitalCMOS.

The HI-8783 is available in a 22 pin DIPformat as a second source replacement for the Micrel / California Devices DLS-111BV. The HI-8783, HI-8784, and HI-8785  offer high speed data bus data transactions to a buffer register. After loading 4 bytes, data is automatically transferred and transmitted. The data rate is equal to theclock rate. Parity canbeenabledinthe32ndbit. Reset is used to initialize the logic upon startup. Word gaps are transmittedautomatically.

The HI-8783, HI-8784, and HI-8785 require+/- 10volt suppliesinadditionto the5 volt supply.
