At 120 kbps the MAX232DR is fast enough for standard UART communication up to 115200 baud with margin. If your design needs RS-232 above 1 Mbps (e.g., for high-speed instrumentation or multi-drop polling), this part is not the right fit — look at the MAX3222 or MAX3232 family for 250 kbps or 1 Mbps options. ## Supply voltage and charge-pump reality It cannot operate at 3.3 V. The internal charge-pump uses four external 1 µF capacitors (typically 0.1 µF to 1 µF ceramic) to generate the ±10 V RS-232 levels. Board area for those caps is part of the footprint budget. It is ROHS3 compliant.","metaTitle":"MAX232DR RS-232 Transceiver, 120 kbps, 16-SOIC","metaDescription":"MAX232DR RS-232 transceiver from Texas Instruments.
