The LTC1518/LTC1519 are high speed, precision delay differential quad bus/line receivers that can operate at data rates as high as 52Mbps. 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 tPLH/tPHL and channel-to-channel skew is 500ps.
Each receiver translates differential input levels (| VID | ≥ 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.
