+5V, RS-232 Transceivers
with 0.1F External Capacitors
Applications Information
Capacitor Selection
The type of capacitor used is not critical for proper
operation. Ceramic capacitors are suggested. To ensure
proper RS-232 signal levels over temperature when
using 0.1FF capacitors, make sure the capacitance
value does not degrade excessively as the temperature
varies. If in doubt, use capacitors with a larger nominal
value. Also observe the capacitors’ ESR value over tem-
perature, since it influences the amount of ripple on V+
and V-. To reduce the output impedance at V+ and V-,
use larger capacitors (up to 10FF). If polarized capaci-
tors are used, obey the polarities shown in Figure 1 and
the pin configurations.
Driving Multiple Receivers
Each transmitter is designed to drive a single receiver.
Transmitters can be paralleled to drive multiple receivers.
Driver Outputs When Exiting Shutdown
Figure 5 shows two driver outputs exiting shutdown. As
they become active, the two driver outputs go to oppo-
site RS-232 levels (one driver input is high, the other
is low). Each driver is loaded with 3kI in parallel with
2500pF. The driver outputs display no ringing or undesir-
able transients as they come out of shutdown.
Power-Supply Decoupling
In applications that are sensitive to power-supply noise,
decouple VCC to ground with a capacitor of the same
value as the charge-pump capacitors.
V+ and V- as Power Supplies
A small amount of power can be drawn from V+ and V-,
although this reduces noise margins.
Power Supplies for MAX201/MAX209
If at power-up the V+ supply rises after the VCC supply,
place a diode (e.g., 1N914) in series with the V+ supply.
