Device Overview
MAX3232ESE+T is a production orderable in the Maxim Integrated MAX3232 family, now supported by Analog Devices. It is a two-driver/two-receiver true RS-232 transceiver that operates from a single 3.0 V to 5.5 V supply and uses an internal dual charge pump to generate RS-232 signal levels.

Engineering Selection Notes
The exact data-rate claim needs care. The broader MAX3222/MAX3232/MAX3237/MAX3241 family includes faster variants, but Analog Devices states that MAX3232 itself is guaranteed for 120 kbps while maintaining RS-232 output levels. The higher-speed MegaBaud mode belongs to MAX3237, so using a family-level speed headline for MAX3232ESE+T would overstate this orderable’s guaranteed rate.
The internal charge pump allows a 3.0 V to 5.5 V logic system to generate true RS-232 voltage levels without a separate bipolar supply, but the minimum capacitor values depend on VCC. At 3.0-3.6 V, 0.1 µF is specified for C1 through C4. At 4.5-5.5 V, C1 can be 0.047 µF while C2 through C4 require 0.33 µF. A design intended to cover the full 3.0-5.5 V supply range should use 0.1 µF for C1 and 0.47 µF for C2, C3, and C4. Place the charge-pump capacitors close to the IC and follow the datasheet decoupling guidance.
The ESE+T order code is the narrow SOIC tape-and-reel variant listed under the MAX3232 product family. It should not be confused with the separate MAX3232E enhanced-ESD family simply because the exact order code contains the letter E.
