FEATURES
DESCRIPTION
The DS14C238 is a four driver, four receiver device
2
Conforms to TIA/EIA-232-E and CCITT V.28
which conforms to the TIA/EIA-232-E standard and
Internal DC-DC Converter
CCITT
V.28
recommendations.
This
device
Operates with Single +5V Supply
eliminates ±12V supplies by employing an internal
DC-DC converter to generate the necessary output
Low Power Requirement—ICC 10 mA max
levels from a single +5V supply. Driver slew rate
Internal Driver Slew Rate Control
control and receiver noise filtering have also been
Receiver Noise Filtering
internalized to eliminate the need for external slew
rate control and noise filtering capacitors.
Operates Above 120 kbits/sec
Direct Replacement for MAX238
