The Maxim MAX3223ECTP+ is a full-duplex RS-232 transceiver integrating two drivers and two receivers in a single 20-TQFN (5x5) package. It handles 250kbps data rate over a 3V to 5.5V supply range, making it a straightforward drop-in for legacy serial ports or new designs needing a compact interface IC. Operating temperature is 0°C to 70°C, so this is a commercial-grade part — not rated for automotive or extended industrial ambient.
Yes, the supply range is 3V to 5.5V, so a 5V rail is within spec. The part operates at full 250kbps data rate across that range.
