HI-8787, HI-8788 January 2001 DESCRIPTION The HI-8787 and HI-8788 are system components for interfacing 16 bit parallel data to an ARINC 429 bus.
They combine logic and line driver on one chip.
The HI-8787 has an output resistance of 37.
5 ohms, and the HI-8788 has output resistance of 10 ohms to facilitate external lightning protection circuitry.
The technology is analog/digital CMOS.
Both products offer high speed data bus transactions into a buffer register.
After loading 2 16-bit words, 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 automa...
