HI-8785 - (HI-8783 - HI-8785) 8 bit parallel data converted to 429 & 561 serial data out

Download the HI-8785 datasheet PDF. This datasheet also covers the HI-8783 variant, as both devices belong to the same (hi-8783 - hi-8785) 8 bit parallel data converted to 429 & 561 serial data out family and are provided as variant models within a single manufacturer datasheet.

Description

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-3182 or HI-8585.

The HI-8784 and HI-8785 combine logic and line driver on one chip.

HI-8783, HI-8784, HI-8785 September 2006 ARINC INTERFACE DEVICE 8 bit parallel data converted to 429 & 561 serial data out PIN CONFIGURATIONS DESCRIPTION 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-3182 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 cicuitry. 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.
