Product details

It handles data rates up to 3 Mbps, making it suitable for high-speed serial links in industrial control, point-of-sale terminals, and telecom equipment where legacy RS232 ports need to keep up with modern throughput. The wide supply range from 3V to 5.5V lets it run off a 3.3V rail or a traditional 5V bus without a separate regulator.

At 3 Mbps this transceiver supports the full RS232 data rate for most applications, including high-speed barcode scanners, industrial PLC links, and debug consoles that push data faster than the classic 115.2 kbps. The 500 mV of receiver hysteresis cleans up noisy lines common in factory-floor cable runs.

Supply voltage and system compatibility

Rated for 3V to 5.5V, the MAX13235EEUP+T works directly on 3.3V logic systems without level shifters, and also drops into legacy 5V RS232 ports.

Housed in a 20-TSSOP (4.40 mm width) with surface-mount termination. The supplier device package is 20-TSSOP, same as the case code.

Frequently asked questions

Is MAX13235EEUP+T compatible with 3.3V systems?

Yes, the supply range of 3V to 5.5V covers 3.3V rails directly. No external level translation is needed for 3.3V logic.

What is the difference between MAX13235EEUP+T and MAX13235EEUP+?

The suffix +T indicates Tape & Reel packaging; the + suffix (without T) typically ships in tubes. The die and electrical specifications are identical.

Can MAX13235EEUP+T replace MAX232?

Both are RS232 transceivers with 2/2 driver/receiver count, but the MAX13235EEUP+T runs at up to 3 Mbps versus the MAX232's typical 120 kbps, and operates from 3V to 5.5V versus the MAX232's 5V-only supply. Pin compatibility depends on the specific layout — check the respective datasheets for pinout differences.
