RS_232C_LED_CIRCUIT

Use a pair of Maxim's 5V-powered MAX231 RS-232C transmitters as drivers to obtain a 2-color LED. The transmitters require only a singleended, 5-V input to generate ±10 V internally.Their outputs are short-circuit-proof and can supply as much as 10 mA-enough to drive most LEDs.Depending on which LED you select, their currentlimiting feature might also eliminate the need for external series resistors. Using the simple circuits, you can implement a variety of functions.
