The 8-SOIC (0.154\", 3.90mm width) footprint is a standard industry layout — the pick-and-place machine sees it as a routine SOP-8 body, and the 1.27 mm pin pitch gives the reflow solder joint enough standoff to avoid tombstoning if the paste volume is balanced across the two rows. The 250 kbps data rate is on the slower side for modern RS-485 links, but that also means the rise/fall times are gentle enough to keep signal-integrity trouble off the board — no special termination or stub-length rules beyond the standard 120 Ω at each bus end. The part is rated for continuous operation in an unheated equipment enclosure or a ventilated panel cabinet; the 85°C ceiling covers most factory-floor ambient conditions short of a direct heat source. ## RS-485 bus interface: what the ratings mean for the BOM Full-duplex operation means the driver and receiver are active simultaneously — the part has separate bus lines for transmit and receive, so a single MAX3488EESA+T handles a point-to-point link without needing to toggle direction. The 1/1 driver/receiver count matches the standard RS-485 node: one driver drives the differential pair, one receiver listens. Receiver hysteresis is 50 mV, which is the typical built-in noise margin for Maxim/Analog Devices RS-485 parts. That 50 mV threshold filters out common-mode noise coupled onto the twisted pair — without it, a floating bus or a lightly loaded line would toggle on every millivolt of crosstalk from adjacent cables. The 250 kbps data rate is specified across the full supply range and temperature band. At 3.0 V supply and 85°C, the driver output differential voltage stays above the 1.5 V minimum the RS-485 standard requires for a valid logic state — no derating needed for worst-case conditions.","metaTitle":"MAX3488EESA+T RS-485/422 Transceiver, 250kbps, 8-SOIC","metaDescription":"MAX3488EESA+T from Analog Devices: full-duplex RS-485/422 transceiver, 3-3.6V supply, 250kbps data rate, 8-SOIC.
