The ICL232 is a dual RS-232 transmitter/receiver interface circuit that meets all ElA RS-232C and V.28 specifications.
It requires a single+5V power supply, and features two onboard charge pump voltage converter swhich generate
+10V and -10V supplies from the 5V supply.

LM139,A - LM239,A - LM339,A LOW POWER QUAD VOLTAGE COMPARATORS These devices consist of four independent precision voltage comparators with an offset voltage specifications as low as 2mV max for LM339A, LM239A and LM139A. All these comparators were designed specifically to operate from a single power supply aver a wide range of voltages. Operation from split power supplies is also possible.

LM124, LM124A, LM224, LM224A, LM324, LM324A, LM2902 QUADRUPLE OPERATIONAL AMPLIFIERS These devices consist of four independent high-gain frequency-compensated operational amplifiers that are designed specifically to operate from a single supply over a wide range of voltages. Operation from split supplies also is possible when the difference between the two supplies is 3 V to 30 V (for the LM2902, 3 V to 26 V) and VCC is at least 1.5 V more positive than the input common-mode voltage. The low supply-current drain is independent of the magnitude of the supply voltage.
