HI-8500
ARINC 429 Line Driver Family
with Tri-State Option
DESCRIPTION
The HI-8500 family is a full-featured ARINC 429 Line Driver
providing three choices of output resistance and a tri-state
option, which allows the outputs to be put in a high-
impedance state.
Like Holt’s industry-standard HI-8585 and HI-8586 ARINC
429 line drivers, the HI-8500 includes digital slew-rate
selection to support high-speed (100kb/s) and low-speed
(12.5kb/s) data rates.
The part is offered in a variety of small footprint packages
including 5mm x 5mm 20-lead plastic QFN package and
traditional 8-pin SOIC package. Ceramic DIPs are also
available.
Inputs are compatible with either 5V or 3.3V logic. Internal
pull-up/down resistors are available on HI-8506 for each
digital input. The resistors are brought out to pins, which
may be externally grounded to hold the ARINC bus in the
null-sate during system power-up, or connected to logic
power to hold the outputs tri-state. This feature is of benefit
when interfacing to field-programmable logic as it defines a
known-state during FPGA initialization, avoiding transient
bus noise at power-on.
The HI-8500 family offers a pin-for-pin drop-in replacement
for the DEI1070A-DEI1075A, DEI1170A and DEI1171A.
See table 1 for exact part number cross references.
