It operates from a single 3V to 5.5V supply, covering both legacy 5V backplanes and modern 3.3V portable designs without an extra regulator.
The exposed pad is typically connected to ground. Verify the pad layout against the datasheet's recommended footprint before committing the board.
ROHS3 compliant. No PCN or LTB has been issued for this order code. For new designs, the MAX3225EETP+T is a safe selection without near-term obsolescence risk.
The transceiver supports a data rate of 1 Mbps. This is sufficient for high-speed RS-232 links such as industrial sensor polling, POS terminals, or debug ports where legacy 115.2 kbps is too slow.
