Product Summary

The LTC1689CS is an ultrahigh speed, differential bus/line driver that can operate at data rates up to 100Mbps. The outputs of the LTC1689CS are Hot Swap capable, maintaining backplane data integrity during board insertion and removal. The LTC1689C allows all four drivers to be enabled together,while the LTC1689 allows two drivers at a time to be enabled. Applications of the LTC1689CS include: High Speed RS485 Twisted-Pair Drivers, High Speed Backplane Drivers, Complementary Clock Drivers, STS-1/OC-1 Data Drivers and SCSI Drivers.
