DESCRIPTION
The LTC
®
488 and LTC489 are low power differential bus/
line receivers designed for multipoint data transmission
standard RS485 applications with extended common
mode range (12V to –7V). They also meet the require-
ments of RS422.
The CMOS design offers significant power savings over
its bipolar counterpart without sacrificing ruggedness
against overload or ESD damage.
The receiver features three-state outputs, with the receiver
output maintaining high impedance over the entire com-
mon mode range.
The receiver has a fail-safe feature which guarantees a
high output state when the inputs are left open.
Both AC and DC specifications are guaranteed 4.75V to
5.25V supply voltage range.
