The LTC1518CS#PBF is a high speed precision delay differential quad bus/line Receiver that can operate at data rates as high as 52Mbps. It is pin compatible with the LTC488/LTC489 RS485 line receivers and operates over the entire -7 to 12V common mode range. Unique architecture provides very stable propagation delays and low skew over wide input common mode, input overdrive and ambient temperature ranges. Propagation delay is 18.5±3.5ns over the commercial temperature range. Typical tPLH/tPHL and channel-to-channel skew is 500ps. Each receiver translates differential input levels into valid CMOS and TTL output levels. Its high input resistance 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.
