DESCRIPTION
FEATURES
PIN CONFIGURATIONS
The HI-8783, HI-8784, and HI-8785 are system compo-
nents for interfacing 8 bit parallel data to an ARINC 429
bus. TheHI-8783isalogicdeviceonlyandrequiresasep-
arate 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
ohmsto facilitateexternallightningprotectioncicuitry. The
technologyisanalog/digitalCMOS.
TheHI-8783isavailableina22pinDIP formatasasecond
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 automati-
cally transferred and transmitted. The data rate is equal to
theclockrate. Paritycanbeenabledinthe32ndbit. Reset
is used to initialize the logic upon startup. Word gaps are
transmittedautomatically.
