It converts 5V logic-level signals to RS232 voltage levels and back, with a data rate of 250 kbps. The part comes in a 16-TSSOP package and operates over the commercial temperature range of 0°C to 70°C. Typical applications include point-of-sale terminals, serial port adapters, and industrial control panels where a single RS232 port is needed on a 5V supply rail. ## 250 kbps — what it means for the serial link The 250 kbps data rate covers standard RS232 baud rates with margin. The 500 mV receiver hysteresis cleans up noisy lines, reducing bit errors on long cable runs without external filtering. ## Lifecycle and sourcing Active product status per the manufacturer — no end-of-life notice, no last-time-buy pressure. ROHS3 compliant.","metaTitle":"MAX221CUE+T RS232 Transceiver, Full Duplex, 250 kbps","metaDescription":"MAX221CUE+T RS232 transceiver from Analog Devices.
