Product details

Active RS232 transceiver for legacy serial links

The MAX231CWE+: Rated for 120 kbps, it covers the classic RS232 band up to the common 115.2 kbps ceiling, with margin for the stop-bit overhead. The 500 mV receiver hysteresis filters out noise on long cable runs — a practical edge for industrial or lab serial links where the ground potential drifts between nodes.

Supply rail flexibility and temperature grade

The part accepts a 5 V logic supply plus a separate charge-pump rail spanning 7.5 V to 13.2 V — the wide V+ range lets it generate the ±10 V RS232 swing from a single 12 V supply or a 9 V battery, without an external DC-DC converter.

SOIC-16 wide-body footprint

The wide-body SOIC also gives better thermal coupling to the PCB copper pour than the narrow SOIC variant.

Frequently asked questions

What is the MAX231CWE+ data rate and how many channels does it support?

It supports 120 kbps data rate with 2 drivers and 2 receivers in full-duplex mode — enough for one bidirectional RS232 port with hardware handshaking lines.

What supply voltages does the MAX231CWE+ need?

It requires a 5 V logic supply (VCC) and a separate charge-pump supply (V+) between 7.5 V and 13.2 V. The internal charge pump generates the RS232 bipolar levels from the V+ rail.

Can I hand-solder the MAX231CWE+?

No hot-air or reflow oven is required.
