Product details

It handles serial data at rates up to 1 Mbps, making it a solid choice for industrial UART links, point-of-sale terminals, and embedded systems that need a reliable serial port without the old 232-level shifters.

Supply voltage flexibility — 3V to 5.5V

Rated for a 3V to 5.5V supply range, this part works cleanly on a 3.3V rail in modern MCU designs or on a legacy 5V bus. No external level translator needed if your logic side matches one of those voltages — the transceiver handles the RS-232 voltage swing internally.

The 500 mV receiver hysteresis helps reject noise on longer cable runs in those environments.

Lifecycle and sourcing posture

No last-time-buy or end-of-life risk for new designs.

Frequently asked questions

Does MAX3225EUP+ work with a 3.3V supply?

Yes, the supply range is 3V to 5.5V, so it operates directly on a 3.3V rail without any modification.

What is the difference between MAX3225EUP+ and MAX3225E?

The MAX3225EUP+ is the lead-free, ROHS3-compliant version in a 20-TSSOP package. The MAX3225E typically refers to the non-lead-free variant or a different package option. Functionally they are the same transceiver, but the MAX3225EUP+ is the current, environmentally compliant ordering code.

Can MAX3225EUP+ replace MAX3225E?

Yes, the MAX3225EUP+ is the direct lead-free replacement for the MAX3225E. It is pin-compatible and electrically identical, so it drops into the same PCB footprint.

What is the difference between MAX3225EUP+ and MAX3225ECUP+?

The MAX3225ECUP+ includes an additional ±15kV ESD protection on the RS-232 bus pins, while the MAX3225EUP+ does not carry that specific ESD rating. Otherwise, both are 2/2 full-duplex transceivers in the same 20-TSSOP package with the same 1 Mbps data rate and supply range.
