Rated for 250kbps data rate, it operates from a 3V to 5.5V supply, covering both 3.3V and 5V logic rails without a separate level translator. The industrial temperature range of -40°C to 85°C makes it a fit for factory automation panels, outdoor telecom gear, and embedded control boards where the ambient temperature swings beyond commercial limits. ## Supply range and data rate — what they mean for the BOM The 3V minimum supply means this part works on a 3.3V rail without a boost converter, saving a regulator slot on mixed-voltage boards. At 250kbps it handles standard UART rates with margin, but falls short of the 1Mbps class. ## Active lifecycle — no obsolescence risk for new designs No last-time-buy or end-of-life notice applies; the part is suitable for new-product introduction and ongoing production builds. ## Package and mounting — board-fit note Housed in a 28-SSOP (0.209\", 5.30mm width) surface-mount package. The supplier device package is also 28-SSOP, so no footprint mismatch between the order code and the actual component.","metaTitle":"MAX3238EAI+ RS-232 Transceiver, 5/3 Drivers, 250kbps","metaDescription":"Maxim MAX3238EAI+ RS-232 full-duplex transceiver: 5 drivers, 3 receivers, 250kbps data rate, 3V–5.5V supply, industrial -40°C to 85°C, 28-SSOP.
