    Products Detail

    The SP490 and SP491 are full-duplex differential transceivers that meet the requirements of RS-485 and RS-422. Fabricated with a Sipex proprietary BiCMOS process, both products require a fraction of the power of older bipolar designs. The SP490 is a low power differential line driver/receiver, while the SP491 adds driver and receiver tri-state enable lines. Both feature ±200mV receiver input sensitivity and a wide common mode range. The SP490 is available in 8-pin plastic DIP and 8-pin NSOIC packages, and the SP491 is available in 14-pin plastic DIP and 14-pin NSOIC packages, for operation over commercial and industrial temperature ranges.

    Key Features

    • • +5V Only • Low Power BiCMOS • Driver/Receiver Enable (SP491) • RS-485 and RS-422 Drivers/Receivers • Pin Compatible with LTC490 and SN75179 (SP490) • Pin Compatible with LTC491 and SN75180 (SP491) • Lead Free Packaging • ±200mV Receiver Input Sensitivity • Wide Common Mode Range (-7V to +12V) • Fail-safe Feature
