DESCRIPTION
The LT^®1030 is an RS232 line driver that operates over a
±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.
