description
The LT1030C is an EIA/TIA-232-F line driver that operates over a ±5-V to ±15-V supply-voltage range on low
supply current. The device can be shut down to zero supply current. Current limiting fully protects the outputs
from externally applied voltages of ±30 V. Since the output swings to within 200 mV of the positive supply and
to within 1 V of the negative supply, supply-voltage requirements are minimized.
A major advantage of the LT1030C is the high-impedance output state when the device is off or powered down.
This feature allows several different drivers on the same bus.
The device can be used as an EIA/TIA-232-F driver, micropower interface, or level translator, among others.
The LT1030C is characterized for operation from 0°C to 70°C.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. All voltage values, except differential voltages, are with respect to GND.
2. The output may be shorted to either supply. Temperature and/or supply voltages must be limited to ensure that the maximum
dissipation rating is not exceeded.
3. The package thermal impedance is calculated in accordance with JESD 51, except for through-hole packages, which use a trace
length of zero.

APPLICATION INFORMATION
forward biasing the substrate
As with other bipolar integrated circuits, forward biasing the substrate diode can cause problems. The LT1030C
draws high current from V to GND when V is open circuited or pulled above ground. Connecting a diode
CC+
CC–
from V
to GND (if possible) prevents the high-current state. Any low-cost diode can be used (see Figure 11).
