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 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.
