LT1781 Low Power 5V RS232 Dual Driver/Receiver with 15kV ESD Protection

LT1780/LT1781 Low Power 5V RS232 Dual Driver/Receiver with ±15kV ESD Protection DESCRIPTIO The LT®1780/LT1781 are dual RS232 driver/receiver pairs with integral charge pump to generate RS232 voltage levels from a single 5V supply. Using only 0.1µF external capacitors, these circuits consume only 40mW of power, and can operate to 120kbaud even while driving heavy capacitive loads. New ESD structures on the chip allow the LT1780/LT1781 to survive ±15kV air gap and ±8kV contact ESD tests per IEC 10.
