HI-8588PST-10

DESCRIPTION

The HI-8588-10 ARINC 429 bus interface receiver is similar to the HI-8588 with the exception that it allows an external 10 Kohm resistor in series with each ARINC input without affecting the ARINC input thresholds. The product is especially useful in applications where lightning protection circuitry is also required. In addition, the test inputs force both of the outputs to zero instead open circuit. The analog/digital CMOS product requires onlya5 volt supply and is available in a SO 8 pin package. Each side of the ARINC bus be connected through a 10 Kohm series resistor in order for the chip to detect the correct ARINC levels. The typical 10 volt differential signal is translated and input to a window comparator and latch. The comparator levels are set so that with the external 10 Kohm resistors they are just below the standard 6.5 volt minimum ARINC data threshold and just above the standard 2.5 voltmaximum ARINC null threshold. The TESTA and TESTB inputs bypass the analog inputs for testing purposes. Also if TESTA and TESTB are both taken high, the digital outputs are forced to zero.

Main Features:

Small package: SO 8-pin package, suitable for space-constrained applications.

ARINC 429 interface: Directly supports ARINC 429 bus communication, suitable for avionics and other fields.

Low voltage operation: only 5V power supply is required, low energy consumption.

Lightning protection: Supports series connection of external resistors to enhance lightning protection capabilities.

Test input function: Provide test input to facilitate debugging and verification.

Multiple packaging and mounting methods: supports plastic and ceramic packaging, as well as surface mount and DIP mounting.

Wide temperature range: adaptable to industrial and extended temperature environments with high stability.

Applications:  

HI-8588PST-10 electronic components are mainly used in the field of avionics data communications. As an ARINC 429 bus interface receiver, it can directly connect to the ARINC 429 bus to achieve data communication with avionics systems and other other devices that comply with the ARINC 429 standard. In addition, its lightning protection and test input capabilities also make it popular in applications requiring high reliability and easy debugging.
