The MAX3311ECUB+: ROHS3 compliant — the part meets the latest EU restriction-of-hazardous-substances directive, so no separate RoHS exemption paperwork is needed for the BOM.
RS232 transceiver — key parametrics for the signal chain
The MAX3311ECUB+ is a single-channel RS232 transceiver with one driver and one receiver, operating in full-duplex mode. The 460 Kbps data rate covers standard RS232 communication for industrial terminals, serial consoles, and point-of-sale equipment — the 500 mV receiver hysteresis filters noise on long cable runs.
Package and board-fit — 10-uMAX/uSOP footprint
The small footprint (roughly 3×3 mm body) fits space-constrained designs where a full DIP or SOIC-16 RS232 transceiver would not. Surface-mount assembly — the tube packaging is standard for prototype and low-volume production. For higher volumes, check with your sourcing desk whether reel packaging is available.
