DS14C238
Single Supply TIA/EIA-232 4 x 4 Driver/Receiver
General Description
The DS14C238 is a four driver, four 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 DC-DC converter to generate the nec-
essary output levels from a single +5V supply. Driver slew
rate control and receiver noise filtering have also been inter-
nalized to eliminate the need for external slew rate control
and noise filtering capacitors.
