DESCRIPTION The SP26LV432 is a quad differential line receiver with 3-State outputs designed to meet the specifications of RS-422. The SP26LV432 Features
Sipex's BiCMOS process allowing low power operational characteristics of CMOS technology while meeting all of the demands of the RS-422 serial protocol over 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 mon 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) mon-mode input voltage range to acmodate ground potential differences.
