DESCRIPTION：

The H1-8588 is an ARINC 429 bus interface receiver and isavailable in a So 8 pin package. The technology isanalog/digital CMOS. The circuitry requires only a 5 voltsupply.

The ARlNC bus can be connected directly to the chip. Thetypical 10 volt differential signal is translated and input to awindow comparator and latch. The comparator levels arejust below the standard 6.5 volt minimum ARINC datathreshold and just above the standard 2.5 volt maximumARINC null threshold.

The TESTA and TESTB inputs bypass the analog fortesting purposes. AlsoifTESTAand TESTB are both takenhigh, the analog powers down and the digital outputs tristate allowing wire-orpossibilities.

Please refer to the H-8588-10 for applications where anexternal resistance in series with the ARINC inputs isrequired for lightning protection or when the digital outputsneed to be a logic zero rather than open circuit whenTESTA and TESTB are both high.See HoltApplication Note AN-300 for more information onlightning protection.
