1 / 12 page  LTC488/LTC489 1 4889fb TYPICAL APPLICATION DESCRIPTION Quad RS485 Line Receiver 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.
