The 500 mV receiver hysteresis filters out noise on long cable runs — a practical edge for industrial or lab serial links where the ground potential drifts between nodes. ## Supply rail flexibility and temperature grade The part accepts a 5 V logic supply plus a separate charge-pump rail spanning 7.5 V to 13.2 V — the wide V+ range lets it generate the ±10 V RS232 swing from a single 12 V supply or a 9 V battery, without an external DC-DC converter. ## SOIC-16 wide-body footprint The wide-body SOIC also gives better thermal coupling to the PCB copper pour than the narrow SOIC variant.","metaTitle":"MAX231CWE+ RS232 Transceiver, 120kbps, 2/2, SOIC-16","metaDescription":"MAX231CWE+ RS232 transceiver from Analog Devices, 2/2 driver/receiver, 120kbps, full duplex, 5V/7.5-13.2V supply, SOIC-16.
