It integrates two drivers and two receivers, handling data rates up to 250 kbps.
At 250 kbps, this transceiver is a good fit for standard RS-232 applications like terminal connections, point-of-sale equipment, and configuration ports. If your design needs to push 1 Mbps or higher — common for some industrial sensor networks or high-speed data loggers — this part won't close the timing. For those cases, look at the MAX3232E family which offers the same pinout but with higher slew-rate-limited data rates.
It is not specified for industrial enclosures, automotive under-hood, or outdoor installations where ambient temperatures drop below freezing or exceed 70°C.
