DS1489/DS1489A Quad Line Receiver
General Description
The DS1489/DS1489Aare quadline receivers designedto
interface data terminal equipment with data communica-
tions equipment. They areconstructedon asinglemonolith- silicon chip. These devices satisfythe specificationsof
EIA Standard RS-232D. The DS1489/DS1489A meetand
exceedthe specificationsof MC1489/MC1489A andare
pin-for-pin replacements.
Features Four separate receiversper package Programmable threshold Built-in input threshold hysteresis ‘‘Fail safe’’ operating mode: high outputfor open inputs Inputs withstand g30V
