LT1030 Quad Low Power Line Driver Features s s s s s s s s 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 limiting. Since the output swings to within 200m V 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. , LTC and LT are registered trademarks of Linear Technology Corporation. - Check patability (some pins may be different).
