It integrates two drivers and two receivers, handling data rates up to 250 kbps over a single 5V supply rail. ## Supply voltage and 3.3V compatibility It is not designed for 3.3V logic systems — the charge-pump architecture needs the 5V rail to generate the ±10V RS-232 output levels. If your design runs on 3.3V only, look at a low-voltage RS-232 transceiver such as the MAX3232 family instead. ## Data rate and receiver hysteresis Rated at 250 kbps, this transceiver covers standard UART speeds up to 115.2 kbps with margin. The supplier device package is 16-PDIP.","metaTitle":"MAX232EING4 RS-232 Transceiver, 2/2 Driver, 250 kbps","metaDescription":"MAX232EING4 RS-232 transceiver from Texas Instruments.
