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.
