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.

The LT1030C draws high current from VCC+ to GND when VCC– is open circuited or pulled above ground. Connecting a diode from VCC– to GND (if possible) prevents the high-current state. Any low-cost diode can be used (see Figure 11). LT1030C 1 14 7 8 1N4001 Figure 11.
