描述 Description

The SP26LV432 is a quad differential line receiver with three-state outputs designed to meet the EIA specifications of the RS-422 serial protocol. The SP26LV432 features Exar's BiCMOS process allowing low power operational characteristics of CMOS technology while meeting all of the demands of the RS-422 serial protocol at 50Mbps under load. The RS-422 protocol allows up to 10 receivers to be connected to a multipoint bus transmission line. The SP26LV432 features a receiver enable control common to all four receivers and a high-Z output with 6mA source and sink capability. Since the cabling can be as long as 4,000 feet, the RS-422 receivers of the SP26LV432 are equipped with a wide (-7.0V to +7.0V) common-mode input voltage range to accommodate ground potential differences.For technical support or help choosing a product please email Exar’s Serial Technical Support group at:?serialtechsupport@exar.com.
