DS14C238
Single Supply TIA/EIA-2324x4 Driver/Receiver
General DescriptionThe DS14C238isa four driver, four receiver device which
conformsto the TIA/EIA-232-E standard and CCITT V.28
recommendations. This device eliminates ±12V suppliesby
employingan internal DC-DC converterto generatethe nec-
essary output levels froma single +5V supply. Driver slew
rate control and receiver noise filtering have also been inter-
nalizedto eliminatethe needfor external slew rate control
and noise filtering capacitors.
Features Conformsto TIA/EIA-232-E and CCITT V.28 Internal DC-DC converter Operates with single +5V supply Low power requirement—ICC10 mA max Internal driver slew rate control Receiver noise filtering Operates above 120 kbits/sec Direct replacementfor MAX238
