HI-8787 - Holt Integrated Circuits

HI-8787 (HI-8787 / HI-8788) 16-BIT PARALLEL DATA CONVERTED 429&561 SERIAL DATA OUT

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 .
