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 requirements of RS422.

The CMOS design offers significant power savings over its bipolar counterpart without sacrificing ruggedness against overload or ESD damage.

The receiver features of LTC488 and LTC489 three-state outputs, with the receiver output maintaining high impedance over the entire common mode range.

The receiver of LTC488 and LTC489 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.
