The MAX3232CDWG4 can support data rates up to 250 kbps, but it's recommended to limit the data rate to 120 kbps for reliable operation.
To ensure reliable operation in noisy environments, it's recommended to use a bypass capacitor (e.g., 0.1 μF) between the VCC and GND pins, and to use a shielded cable for the RS-232 interface.
The MAX3232CDWG4 has an operating temperature range of -40°C to 85°C.
Yes, the MAX3232CDWG4 can operate from a 3.3V supply, but the output voltage levels will be reduced accordingly. The device is specified to operate from 3.0V to 5.5V.
To enter shutdown mode, the SHDN pin should be driven low. In shutdown mode, the device consumes very low power (typically < 1 μA) and the RS-232 outputs are high-impedance.
