Product Summary

The LTC1518IS#TR is a high speed, precision delay differential quad bus/line receiver 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. Typical tPLH/tPHL and channel-to-channel skew is 500ps. The applications of the LTC1518IS#TR include High Speed RS485/RS422 Receivers, STS-1/OC-1 Data Receivers, PECL Line Receivers, Level Translators, Fast-20/Fast-40 SCSI Receiver.
