DS14C241
Single Supply TIA/EIA-232 4 x 5 Driver/Receiver
General Description
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
employing an internal DC–DC 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
TRI-STATE
power consumption is kept to a minimum.
