LTC488/LTC489

Quad RS485 Line Receiver

FEATURES

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.

trademarks are the property of their respective owners.
