SP26LV432
HIGH SPEED +3.3V QUAD RS-422 DIFFERENTIAL LINE RECEIVER
SEPTEMBER 2008
REV. 1.0.0
GENERAL 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.
