HI-8783, HI-8784, HI-8785
The HI-8784 and HI-8785 have the same digital logic func-
tion as the HI-8783, but include an on-chip line driver de-
signedtodirectlydrivetheARINC429bus.ThetwoARINC
outputs(TXAOUTandTXBOUT)provideadifferentialvolt-
age to produce a +10 volt One, a -10 volt Zero, and a 0 volt
Null. The slope of the ARINC outputs is controlled by the
SLP1.5 pin.IfSLP1.5is high,theoutputriseandfalltimeis
nominally 1.5us. If SLP1.5 is set low, the rise and fall times
are10us.DATAONEandDATAZEROoutputsarenotpro-
videdfortheHI-8784andHI-8785.
The HI-8784 has 37.5 ohms in series with each line driver
output. The HI-8785 has 10.0 ohms in series. The HI-8785
is for applications where external series resistance is
needed,typicallyforlightningprotectiondevices.
