The 500 kbps data rate is fast enough for most industrial UART applications (115200 baud is typical), but if you need higher throughput, you will be looking at a different transceiver family. Receiver hysteresis of 300 mV provides noise immunity on the incoming serial lines, which matters in electrically noisy environments like motor drives or relay panels.","metaTitle":"MAX3222EIDBR RS-232 Transceiver, 500 kbps, 20-SSOP","metaDescription":"TI MAX3222EIDBR RS-232 transceiver, 2/2 drivers/receivers, 500 kbps data rate, 3V-5.5V supply, -40°C to 85°C, 20-SSOP.
