The DS14C241 is four driver, five receiver device which conforms to the TIA/EIA-232-E standard and CCITT V.28 recommendations. This device eliminates 12V supplies by employing an internal DCDC converter to generate the necessary output levels from a single +5V supply. Driver slew rate control and receiver noise filtering have also been internalized to eliminate the need for external slew rate control and noise filtering capacitors. With the addition of TRISTATE receiver outputs and a shutdown mode, device power consumption is kept to a minimum.
