DATA RDY
OUTPUT
Receiver data ready flag. A high level indicates data is available in the receive
buffer. Flag goes low when the first 8-bit byte is read.
D0 to D7
OUTPUT
8-bit parallel data bus (tri-state)
GND
POWER
0V
INPUT
Read strobe. A low level transfers receive buffer data to the data bus
PARITY ENB
INPUT
Parity Enable - A high level activates odd parity checking which replaces the
32nd ARINC bit with an error bit. Otherwise, the 32nd ARINC bit is unchanged
ERROR
OUTPUT
Error Flag. A high level indicates a bit count error (number of ARINC bits was
less than or greater than 32) and/or a parity error if parity detection was enabled
(PARITY ENB high)
INA
INPUT
Positive digital serial data input (HI-8683 only)
INB
INPUT
Negative digital serial data input (HI-8683 only)
RINA/RINA-10
INPUT
Positive direct ARINC serial data input
RINB/RINB-10
INPUT
Negative direct ARINC serial data input (HI-8684 & HI-8684-10 only)
INPUT
Internal logic states are initialized with a low level
TESTA
INPUT
Used in conjunction with the TESTB input to bypass the built-in analog line
receiver circuitry
TESTB
INPUT
U
GAPCLK
INPUT
Gap Clock. Determines the minimum time required between ARINC words for
detection. The minimum word gap time is between 16 and 17 clock cycles of
this signal.

FUNCTIONAL DESCRIPTION
The HI-8683 and HI-8684 are serial to 8-bit parallel convert-
ers. The incoming data stream is serially shifted into an input
register, checked for errors, and then transferred in parallel to
a 32-bit receive buffer. The receive data can be accessed us-
ing four 8-bit parallel read operations while the next serial
data steam is being received.
Figure 1 is a block diagram of both the HI-8683 and HI-8684.
The difference between the two products is the HI-8684 has
a built-in line receiver whereas the HI-8683 is strictly a digital
device and requires an external ARINC line receiver such as
the Holt HI-8444, HI-8445, HI-8448 , HI-8482 or HI-8588 to in-
terface to the ARINC 429 bus.
RECEIVER INPUTS
HI-8684 Line Receiver
Internal 35K
resistors are in series with both the RINA and
RINB ARINC 429 inputs. They connect to level translators
whose resistance to GND is typically 10K
After level trans-
lation, the buffered inputs drive a differential amplifier. The
differential signal is compared to levels derived from a divider
between VCC and GND. The nominal settings correspond to
a One/Zero amplitude of 6.0V and a Null amplitude of 3.3V. A
valid ARINC One/Zero input sets a latch and a Null input re-
sets the latch.
Since any added external series resistance will affect the volt-
age translation, the HI-8684-10 is available with 25K
of the
35K
series resistance required for proper ARINC 429 level
detection. The remaining 10K
required that must be added
can be incorporated in other external circuitry such as light-
ning protection. Except for the different input series resis-
tance, the HI-8684 and HI-8684-10 are identical.
