Isolated RS-232 Transceivers

Maxim created the MAX3250, a +50V isolated transceiver capable of withstanding damage if the transmission lines are inadvertently short-circuited to a +24 or +48V power bus. The MAX3250 is a low cost replacement for opto-isolated transceivers. Maxim's propriety isolation method is inductorless and transformerless simplifying EMI compliance.

Package Size

Maxim developed the world's smallest RS-232 receivers and transmitters available in a tiny SOT23-5 package. These parts are optimized for low power space saving applications with shutdown currents as low a 0.2uA. The MAX3189E and the MAX3190E are excellent examples of RS-232 SOT23-5 transmitters with low shutdown current, and are complimented with the MAX3180E family of receivers.
