Invalid Signal Detector Output, active low. A logic high indicates that a valid RS-232
level is present on a receiver.

RS-232 Transmitter Outputs
FORCEON
Force-On Input, active high. Drive high to override AutoShutdown Plus, keeping
transmitters and receivers active (FORCEOFF must be high) (Table 1).

RS-232 Receiver Outputs
C1+
Positive terminal of the internal voltage-doubling charge-pump capacitor. Leave
unconnected or connect to an external 0.1F capacitor. See
Charge Pump Section.
VCC
Supply Voltage (MAX3233E = +3.3V, MAX3235E = +5.0V)
FORCEOFF
Force-Off Input, active low. Drive low to shut down transmitters, receivers, and charge
pump. This overrides AutoShutdown Plus and FORCEON (Table 1).
V+
+5.5V generated by the charge pump. Do not connect.
C1-
Negative terminal of the internal voltage-doubling charge-pump capacitor. Leave
unconnected or connect to an external 0.1F capacitor. See
Charge Pump Section.
C2+
Positive terminal of the internal inverting charge-pump capacitor. Do not connect.
C2-
Negative terminal of the internal inverting charge-pump capacitor. Do not connect.
V-
-5.5V generated by the charge pump. Do not connect.
