Supply Voltage. +2.5V to +5.5V supply voltage.
Inverting Charge-Pump Capacitor Positive Terminal
Inverting Charge-Pump Capacitor Negative Terminal
Negative Charge-Pump Output. -5.5V/-4.0V generated by charge pump.
Logic Voltage Input. Logic-level input for receiver outputs and transmitter inputs.
Connect V L to the system-logic supply voltage or V CC if no logic supply is required.
Transmitter Input(s)
Positive Charge-Pump Output. +5.5V/+4.0V generated by charge pump. If charge
pump is generating +4.0V, the device has switched from RS-232-compliant to RS-232-
compatible mode.
No Connection. The MAX3230E/MAX3231E are not populated with solder bumps at
these locations. The MAX3230AE/MAX3231AE are populated with electrically isolated
solder bumps at these locations.
Active High FORCEON Input. Drive FORCEON high to override automatic circuitry,
keeping transmitters and charge pumps on.
Positive Regulated Charge-Pump Capacitor Positive Terminal
Active-Low FORCEOFF Input. Drive FORCEOFF low to shut down transmitters,
receivers, and on-board charge pump. This overrides all automatic circuitry and
FORCEON.
