The single-supply range from 3V to 5.5V means the transceiver can run off a 3.3V logic rail or a 5V legacy bus without a separate RS-232 charge-pump supply, reducing BOM count. ## Active production, ROHS3, and sourcing posture For BOM planning: the part is sourced per RFQ against your quantity.","metaTitle":"MAX3223MDBREP RS-232 Transceiver - Texas Instruments","metaDescription":"MAX3223MDBREP RS-232 transceiver, 2/2 driver/receiver, 250 kbps, 3V-5.5V supply, -55°C to 125°C, 20-SSOP.

The MAX3223MDBREP is a 20-SSOP surface-mount part with the -55°C to 125°C range. They are not pin-compatible; verify the board footprint and environmental requirements before substituting."},{"question":"What is the difference between MAX3223 and MAX3232?","answer":"The MAX3223 is a 2-driver/2-receiver full-duplex transceiver. The MAX3232 is also a 2/2 device but typically operates at a lower data rate (250 kbps vs 250 kbps — same nominal rate) and may have different receiver hysteresis or supply range.
