Detailed Description
The MAX200–MAX209/MAX211/MAX213 consist of

(transmitters), and receivers. Each section is described
in detail.

The +5V to
Q10V
conversion is performed by two
charge-pump voltage converters (Figure 4). The first
uses capacitor C1 to double +5V to +10V, storing +10V
on the V+ output filter capacitor, C3. The second charge-
pump voltage converter uses capacitor C2 to invert +10V
to -10V, storing -10V on the V- output filter capacitor, C4.
The MAX201 and MAX209 include only the V+ to V-
charge pump, and are intended for applications that
have a V
CC
= +5V supply and a V+ supply in the +9V to
+13.2V range.
In shutdown mode, V+ is internally connected to V
CC
by
a 1kI pulldown resistor and V- is internally connected to
ground by a 1kI pullup resistor.
When V
CC
= +5V, the typical driver output-voltage swing
is
Q8V
when loaded with a nominal 5kI RS-232 receiver.
The output swing is guaranteed to meet the EIA/TIA-232E
and V.28 specifications, which call for
Q5V
minimum out-
put levels under worst-case conditions. These include
a minimum 3kI load, V
CC
= +4.5V, and the maximum
operating temperature. The open-circuit output-voltage
swing ranges from (V+ - 0.6V) to V-.
Input thresholds are both CMOS and TTL compatible.
The inputs of unused drivers can be left unconnected
since 400kI pullup resistors to V
CC
are included on-
chip. Since all drivers invert, the pullup resistors force
the outputs of unused drivers low. The input pullup resis-
tors typically source 15µA; therefore, the driver inputs
should be driven high or open circuited to minimize
power-supply current in shutdown mode.
When in low-power shutdown mode, the driver outputs
are turned off and their leakage current is less than 1mA,
even if the transmitter output is backdriven between 0V
and (V
CC
+ 6V). Below -0.5V, the transmitter output is
diode clamped to ground with a 1kI series impedance.
The transmitter output is also zener clamped to approxi-
mately (V
CC
+ 6V), with a 1kI series impedance.
