DS1489A - Quad Line Driver

Download the DS1489A datasheet PDF. This datasheet also covers the DS1489 variant, as both devices belong to the same quad line driver family and are provided as variant models within a single manufacturer datasheet.

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.
