RS232 transceiver for 5V-only serial ports
The MAX208CWG+T is a full-duplex RS232 transceiver integrating four drivers and four receivers in a single 24-SOIC package — a drop-in for legacy serial ports that need to convert 5V logic levels to RS232 voltage swings without external level shifters. Rated for a 120kbps data rate, this part covers standard UART speeds up to 115.2kbps with margin; the 500 mV receiver hysteresis filters out noise on long cable runs, reducing false start-bit detection.
