Part Information
MAX232ECWE+T image
RoHS Compliant
The MAX202E-MAX213E, MAX232E, and MAX241E are a family of RS-232 and V.28 transceivers with high ±15kV ESD HBM protection and integrated charge pump circuit- ry for single +5V supply operation. The various combina- tions of features are outlined in the Selector Guide. The drivers and receivers for all ten devices meet all EIA/TIA- 232E and CCITT V.28 specifications at data rates up to 120kbps when loaded. The MAX211E/MAX213E/MAX241E are available in 28- pin SO and SSOP packages. The MAX202E/MAX232E come in 16-pin TSSOP, narrow SO, wide SO, and DIP packages. The MAX203E comes in a 20-pin DIP/SO package, and needs no external charge-pump capaci- tors. The MAX205E comes in a 24-pin wide DIP pack- age, and also eliminates external charge-pump capacitors.

Engineer Comments

RS232 is, in many ways, a living fossil. While the relatively low data rates don't qualify the protocol as a high-speed communication interface, it's robustness and ease of implementation nevertheless make it attractive.

One of Dallas Maxim's absolute evergreens is the MAX232- a nifty transceiver IC which makes use of a capacitor based voltage boosting circuit to generate the voltage levels needed for fullly protocol compliant RS232 communication.

Having a second source makes evergreens even more popular. Texas Instruments is an international semiconductor powerhouse, and has been offering a second source alternative for quite some time. If you ever need to perform a fully protocol compliant RS232 communication and don't have access to the needed voltage levels, don't burden your design with complex boost regulators.

Instead, do it like the elders have done - a MAX232, a few capacitors, and have a happy day. The part is available in a DIP housing: convenient for small scale production and prototyping.
