They are pin compatible with the LTC488/LTC489 RS485 line receivers and operate over the entire ?7V to 12V common mode range. A unique architecture provides very stable propagation delays and low skew over wide input common mode, input overdrive and ambient temperature ranges. Propagation delay is 18.5ns ?3.5ns over the commercial temperature range. Typical t PLH /t PHL and channel-to-channel skew is 500ps.Each receiver translates differential input levels (|V ID | >= 300mV) into valid CMOS and TTL output levels. Its high input resistance (>=22k) allows many receivers to be connected to the same driver. The receiver outputs go into a high impedance state when disabled. The receivers have a fail-safe feature that guarantees a high output state when the inputs are shorted or left floating. Other protection features include thermal shutdown and a controlled maximum short-circuit current (50mA Max). Input resistance remains >=22k when the device is unpowered or disabled, thus allowing hot swapping without loading the data lines.The LTC1518/LTC1519 operate from a single 5V supply and draw 12mA of supply current.
