DESCRIPTION
The DS14C335 is three driver, five receiver device
which conforms to TIA/EIA-232-E and CCITT V.28
standard specifications. 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 current
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 applications.
