DS14C241 Single Supply TIA/EIA-232 4 x 5 Driver/Receiver

May 1998

DS14C241

Single Supply TIA/EIA-232 4 x 5 Driver/Receiver

General Description

The DS14C241 is four driver, five receiver device which con-

forms to the TIA/EIA-232-E standard and CCITT V.28 recom-

mendations. This device eliminates

鹵

12V supplies by em-

ploying an internal DC鈥揇C 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 con-

trol and noise filtering capacitors. With the addition of TRI-

STATE

廬

receiver outputs and a shutdown mode, device

power consumption is kept to a minimum.
