DS14C238

Single Supply TIA/EIA-2324x4 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

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.
