LTC1689CS#PBF

LTC1689 is an ultrahigh speed, differential bus/line driver. This device operate over the full RS485 common mode range (-7V to 12V), and also meet RS422 requirements. The driver outputs are Hot Swap capable, maintaining backplane data integrity during board insertion and removal. This driver feature three-state outputs, maintaining high impedance over the entire common mode range (-7V to 12V). Outputs also remain high impedance during power-up and with the power off. A short-circuit feature detects bus contention and substantially reduces driver output current. Thermal shutdown circuitry protects the parts from excessive power dissipation. It is widely used in application such as high speed RS485 twisted-pair drivers, high speed backplane drivers, complementary clock drivers, STS-1/OC-1 data drivers, SCSI drivers etc.

• Single 5V or 3V supply
• Input current is 1µA typical
• Operating temperature is 0°C to 70°C
• Package style is 16-lead plastic SO
