hi-8783 Summary of contents
Page 1
... 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 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 ...

... FUNCTIONAL DESCRIPTION The HI-8783 is a parallel to serial converter, which when loaded with four eight bit parallel bytes, outputs the data bit serial word. Timing circuitry inserts a 4 bit gap at the end of each 32 bit word. An input buffer register allows load operations to take place while the previously loaded word is being transmitted ...

... BUS FUNCTIONAL DESCRIPTION (Cont.) The HI-8784 and HI-8785 have the same digital logic func- tion as the HI-8783, but include an on-chip line driver de- signed to directly drive the ARINC 429 bus. The two ARINC outputs (TXAOUT and TXBOUT) provide a differential volt- age to produce a +10 volt One, a -10 volt Zero, and a 0 volt Null ...
