The LTC^®1688/LTC1689 are ultrahigh speed, differential

bus/line drivers that can operate at data rates up to

100Mbps. Propagation delay is guaranteed at 8ns ±4ns

over the full operating temperature range. These devices

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. The drivers feature three-state outputs, maintain-

ing 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.

■

Thermal Shutdown Protected

Single 5V or 3V Supply

Pin Compatible with LTC486/LTC487

APPLICATIO S

■

The LTC1688 allows all four drivers to be enabled together,

while the LTC1689 allows two drivers at a time to be

enabled.

High Speed RS485 Twisted-Pair Drivers

High Speed Backplane Drivers

Complementary Clock Drivers

STS-1/OC-1 Data Drivers

■

The LTC1688/LTC1689 operate from a single 5V or 3V

supply and draw only 9mA of supply current.
