Микросхема HOLT, HI-8784PST

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-8382 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 circuitry. 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.

The products 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 the clock rate. Parity can be enabled in the 32nd bit. Reset is used to initialize the logic upon startup. Word gaps are transmitted automatically.

The HI-8784 and HI-8785 require +/- 10 volt supplies in addition to the 5 volt supply.
