Product details

RS-232 transceiver for industrial serial links

It handles data rates up to 1 Mbps, making it suitable for applications that need faster throughput than standard 115.2 kbps RS-232 links. The wide supply range from 3 V to 5.5 V lets it operate from a single 3.3 V or 5 V rail without an extra regulator, simplifying power distribution in mixed-voltage designs.

The 1 Mbps data rate is the headline spec: it supports high-speed RS-232 links for applications like industrial barcode scanners, PLC programming ports, or debug consoles that need to push firmware updates quickly. At this rate, the receiver hysteresis of 500 mV provides noise immunity on the incoming signal, reducing the chance of bit errors on a long cable run in an electrically noisy factory floor. The full-duplex capability means the driver and receiver can operate simultaneously, which is useful for protocols that require continuous transmit and receive without bus turnaround delays.

Supply voltage and temperature grade — fit for the BOM

The 3 V to 5.5 V supply range covers common logic rails: 3.3 V for low-power MCUs and FPGAs, and 5 V for legacy industrial controllers or +5 V-only backplanes.

Frequently asked questions

Is MAX3227EAAE+ RoHS compliant?

Yes, the MAX3227EAAE+ is ROHS3 compliant, meeting the current EU restriction requirements for lead-free soldering.

Does MAX3227EAAE+ require external capacitors?

RS-232 transceivers typically require external charge-pump capacitors for the voltage doubler and inverter that generate the ±5V to ±10V RS-232 levels. The datasheet provides the recommended capacitor values and connections. This part is no exception — plan for four external capacitors in the BOM.
