The 500 mV receiver hysteresis filters noise on the incoming line — a practical margin for cables running alongside switching supplies in an industrial backplane. ## Why the SN65HVD233MDREP is not a second-source It operates from 3.0V supply and comes in a different package family. It will not drop into a board designed for the MAX232DW — the pinout, protocol, and supply rails are incompatible. No cross-reference exists between these two parts.","metaTitle":"Texas Instruments MAX232DW RS232 Transceiver, Full Duplex","metaDescription":"Texas Instruments MAX232DW RS232 transceiver, full duplex, 2/2 drivers/receivers, 120Kbps, 4.5V-5.5V, 0-70°C, 16-SOIC.
