DS1489/DS1489A
Quad Line Receiver
General Description
The DS1489/DS1489A are quad line receivers designed to
interface data terminal equipment with data communications
equipment. They are constructed on a single monolithic
silicon chip. These devices satisfy the specifications of EIA
Standard RS-232D. The DS1489/DS1489A meet and ex-
ceed the specifications of MC1489/MC1489A and are
pin-for-pin replacements.
