DS14C335
+3.3V Supply TIA/EIA-232 3 x 5 Driver/Receiver
General Description
The DS14C335 is three driver, five receiver device which
conforms to TIA/EIA-232-E and CCITT V.28 standard speci-
fications. This device employs an internal DC-DC converter
to generate the necessary output levels from a +3.3V power
supply. A SHUTDOWN (SD) mode reduces the supply cur-
rent to 10 µA maximum. In the SD mode, one receiver is
active, allowing ring indicator (RI) to be monitored. PC Board
space consumption is minimized by the availability of Shrink
Small Outline Packaging (SSOP).
This device’s low power requirement and small footprint
makes it an ideal choice for Laptop and Notebook applica-
tions.
