DESCRIPTION

TheHI-1567andHI-1568arelowpowerCMOSdual
transceiversdesignedtomeettherequirementsof
MIL-STD-1553/1760specifications.

Thetransmittersectionofeachchanneltakes
complimentaryCMOS/TTLdigitalinputdataandconverts
ittobi-phaseManchesterencoded1553signalssuitable
fordrivingthebusisolationtransformer.Separate
transmitterinhibitcontrolsignalsareprovidedforeach
