HI-8683, HI-8684
ARINC INTERFACE DEVICE
ARINC 429 & 561 Serial Data to 8-Bit Parallel Data
DESCRIPTION
The HI-8683 and HI-8684 are system components for
interfacing incoming ARINC 429 signals to 8-bit parallel
data using proven +5V analog/digital CMOS technology.
The HI-8683 is a digital device that requires an external
analog line receiver such as the HI-8482 or HI-8588
between the ARINC bus and the device inputs. The HI-8684
incorporates the digital logic and analog line receiver
circuitry in a single device.
The HI-8683 is also available as a second source to the
DLS-112 with the original 18 pin DIP and 28 pin PLCC
package pinouts.
The receivers on the HI-8684 connect directly to the ARINC
429 Bus and translate the incoming signals to normal CMOS
levels. Internal comparator levels are set just below the
standard 6.5 volt minimum data threshold and just above the
standard 2.5 volt maximum null threshold. The -10 version
of the HI-8684 allows the incorporation of an external 10KΩ
resistance in series with each ARINC input for lightning
protection without affecting ARINC level detection.
Both products offer high speed 8-bit parallel bus interface, a
32-bit buffer, and error detection for word length and parity.
A reset pin is also provided for power-on initialization.
FEATURES
! Automatic conversion of serial ARINC 429, 575 &
561 data to 8-bit parallel data
! High speed parallel 8-bit data bus
! Error detection - word length and parity
! Reset input for power-on initialization
! On-chip line receiver option (HI-8684)
! Input hysteresis of at least 2 volts (HI-8684)
! Test inputs bypass analog inputs (HI-8684)
! Simplified lightning protection with the ability to add
10 Kohm external series resistors (HI-8684-10)
! Plastic package options - surface mount (SOIC),
PLCC and DIP
! Military processing available
