It handles data rates up to 460 kbps over a 4.5V to 5.5V supply rail, with 500 mV of receiver hysteresis for noise immunity on the serial line. The commercial temperature range (0°C to 70°C) suits it for bench equipment, point-of-sale terminals, and other indoor serial interfaces where the ambient stays within that band. ## Sourcing and lifecycle — still in active production It is ROHS3 compliant. For a BOM line that needs a 5V RS-232 transceiver in the 10-uMAX/uSOP footprint, this part is a straightforward fit with no last-time-buy risk. ## 5V supply only — plan the power rail accordingly The supply range is 4.5V to 5.5V, so this transceiver runs from a clean 5V rail — not 3.3V. If your system uses 3.3V logic, the receiver output is still 5V-level, so a level translator or a 5V-tolerant UART input is needed on the controller side. The 500 mV receiver hysteresis helps reject line noise on longer cable runs, which is useful for RS-232 links in electrically noisy environments like a lab bench or a production floor. ## Footprint and handling note The 10-TFSOP / 10-MSOP (3.00 mm width) package is a common small-outline footprint. It is surface-mount only, so plan for reflow soldering. The supplier device package is listed as 10-uMAX/uSOP; the same land pattern covers both the uMAX and uSOP variants. No exposed thermal pad — dissipation is through the package body and pins.","metaTitle":"MAX3311CUB+ RS-232 Transceiver, 460 kbps, 5V, 10-uMAX/uSOP","metaDescription":"MAX3311CUB+ is an active RS-232 transceiver from Maxim Integrated.
