RS-232 link at 1 Mbps with wide supply tolerance
The MAX3225EEUP+T is an RS-232 transceiver delivering full-duplex communication at 1 Mbps over a 3V to 5.5V supply range — covering both legacy 5V and modern 3.3V logic rails without a separate level shifter. The 2/2 driver/receiver count suits point-to-point or basic multi-drop links in industrial serial interfaces. Receiver hysteresis of 500 mV improves noise immunity on long cable runs, reducing bit errors in electrically noisy environments like motor drives or factory-floor panels.
Industrial temperature grade and footprint
The 20-TSSOP package (4.40 mm width) keeps the PCB footprint compact for space-constrained designs.
Active production — no lifecycle risk
No end-of-life notice or successor has been issued, making it a stable BOM line for both new designs and sustaining builds.
