All models in this series feature low-power CMOS construction and Exar Patented (5,306,954) on-board charge pump circuitry to generate the +/- 0V RS-232 voltage levels, using 0. F charge pump capacitors to save board space and reduce circuit cost. The SP206 and SP2 models feature a low-power shutdown mode which reduces power sup - ply drain to A.
