description
The MAX3232 device consists of two line drivers, two line receivers, and a dual charge-pump circuit with
±15-kV ESD protection pin to pin (serial-port connection pins, including GND). The device meets the
requirements of TIA/EIA-232-F and provides the electrical interface between an asynchronous communication
controller and the serial-port connector. The charge pump and four small external capacitors allow operation
from a single 3-V to 5.5-V supply. The devices operate at data signaling rates up to 250 kbit/s and a maximum
of 30-V/µs driver output slew rate.
The MAX3232C is characterized for operation from 0°C to 70°C. The MAX3232I is characterized for operation
from –40°C to 85°C.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. All voltages are with respect to network GND.
2. The package thermal impedance is calculated in accordance with JESD 51.
