description

The LTC®488 and LTC499 are low-power differential bus/line receivers designed for multipoint data transmission standard RS485 applications with an extended common-mode range (12V to -7V). They are also RS422 compliant. Compared to its bipolar counterpart, the CMOS design offers significant energy savings without sacrificing ruggedness against overload or ESD damage. The receiver has a three-state output, and the receiver output maintains high impedance over the entire common-mode range. The receiver has a fail-safe feature that ensures a high output state when the input is placed in an open circuit state. Both AC and DC specifications of the device are guaranteed over a supply voltage range of 4.75V to 5.25V.
