RS-232 link for mixed-voltage boards
The MAX3227EETE+ is a single-channel RS-232 transceiver from Analog Devices, handling one driver and one receiver in a full-duplex configuration at data rates up to 1 Mbps. Its supply voltage range of 3V to 5.5V lets it bridge between a 3.3V logic core and legacy 5V RS-232 peripherals without a separate level translator — the charge pump on-chip generates the bipolar RS-232 levels from a single rail.
