FEATURES
DESCRIPTION
The DS14C535 is three driver, five receiver device
which conforms to EIA/TIA-232-E and CCITT (ITU-T)
V.28 standard specifications. This device employs an
internal DC-DC converter to generate the necessary

output levels from
a
+5V 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).

Operates with Single +5V Power Supply
Low Power Requirement—ICC 12 mA Maximum
SHUTDOWN Mode—ICX 10 μA Maximum
One Receiver (R5) Active During SHUTDOWN
The DS14C535 provides a one-chip solution for the
common 9-pin serial RS-232 interface between data
terminal and data circuit-terminating equipment.
Operates up to 128 kbps—Lap-Link

4V/μs Minimum Slew Rate Ensured
This device allows an easy migration path to the 3.3V
DS14C335. The packages are the same. The N/C
pins on the DS14C535 are not physically connected
to the chip. Board layout for the DS14C335 will
accommodate both devices.
ESD Rating of 3 kV on All Pins (H, B, M)
Available in 28-lead SSOP EIAJ Type II

Only Four 0.1 μF Capacitors Required for the
DC-DC Converter
This device's low power requirement and small
footprint makes it an ideal choice for Laptop and
Notebook applications.
