Output of Several Devices Can Be Paralleled

The LT

±5V to ±15V range on low supply current and can be shut

down to zero supply current. Outputs are fully protected

from externally applied voltages of

±30V by current limit-

ing. Since the output swings to within 200mV of the

positive supply and 1V of the negative supply, power

supply needs are minimized.

A major advantage of the LT1030 is the high impedance

output state when off or powered down, which allows

several different drivers on the same bus.

Our RS232 product line includes other high performance

devices. The LT1039 is a triple low power driver/receiver

with shutdown that can be powered from a 5V supply. The

LT1080 is a 5V powered dual driver/receiver with on-chip

±9V power generator and shutdown.
