+5V, RS-232 Transceivers
with 0.1µF External Capacitors
General Description
Next-Generation Device Features
S For Low-Cost Applications:
The MAX200–MAX209/MAX211/MAX213 transceivers
are designed for RS-232 and V.28 communication inter-
faces where Q12V supplies are not available. On-board
charge pumps convert the +5V input to the Q10V needed
for RS-232 output levels. The MAX201 and MAX209
operate from +5V and +12V, respectively, and contain a
+12V to -12V charge-pump voltage converter.
MAX221E: 15kV ESD-Protected, +5V, 1µA,
Single RS-232 Transceiver with AutoShutdown™
S For Low-Voltage and Space-Constrained Applications:
MAX3222E/MAX3232E/MAX3237E/MAX3241E/
MAX3246E: 15kV ESD-Protected, Down
to 10nA, +3.0V to +5.5V, Up to 1Mbps, True
RS-232 Transceivers (MAX3246E Available in
UCSP™ Package)
The MAX200–MAX209/MAX211/MAX213 drivers and
receivers meet all EIA/TIA-232E and CCITT V.28 speci-
fications at a 20kbps data rate. The drivers maintain the
Q5V EIA/TIA-232E output signal levels at data rates in
excess of 120kbps when loaded in accordance with the
EIA/TIA-232E specification.
S For Space-Constrained Applications:
MAX3228E/MAX3229E: 15kV ESD-Protected,
+2.5V to +5.5V, RS-232 Transceivers in UCSP
S For Low-Voltage or Data Cable Applications:
MAX3380E/MAX3381E: +2.35V to +5.5V, 1µA,
2Tx/2Rx RS-232 Transceivers with 15kV ESD-
Protected I/O and Logic Pins
The 5FW shutdown mode of the MAX200, MAX205,
MAX206, and MAX211 conserves energy in battery-pow-
ered systems. The MAX213 has an active-low shutdown
and an active-high receiver enable control. Two receiv-
ers of the MAX213 are active, allowing the ring indicator
(RI) to be monitored easily using only 75FW power.
S For Low-Power Applications:
MAX3224E–MAX3227E/MAX3244E/MAX3245E:
15kV ESD-Protected, 1µA, 1Mbps,
+3.0V to +5.5V, RS-232 Transceivers with
AutoShutdown Plus™
The MAX211 and MAX213 are available in a 28-pin, wide
small-outline (SO) package and a 28-pin shrink small-
outline (SSOP) package, which occupies only 40% of the
area of the SO. The MAX207 is now available in a 24-pin
SO package and a 24-pin SSOP. The MAX203 and
MAX205 use no external components and are recom-
mended for applications with limited circuit board space.
