It operates from a 4.75 V to 5.25 V supply and supports both full and half-duplex communication at a data rate of 250 kbps. ## Supply rail and data-rate constraints The 5 V ±5 % supply rail is fixed — this part does not run on 3.3 V. At 250 kbps, the maximum cable length follows the RS-485 trade-off: roughly 4000 ft at that speed, limited by signal rise-time and DC drop. The single driver and single receiver cover point-to-point or multi-drop topologies with proper termination. Housed in a 28-SSOP package with 0.209-inch body width and 5.30 mm height, surface-mount. The 0.65 mm pin pitch requires a 4-layer board for clean fan-out of the isolation barrier signals. No exposed pad — thermal dissipation relies on copper pours under the package. ## Sourcing and compliance note Active lifecycle status means no end-of-life risk for ongoing production. RoHS non-compliant — verify your assembly line's exemption policy if you require lead-free solder.","metaTitle":"MAX3158EAI RS-485/RS-422 Transceiver with Isolation –","metaDescription":"MAX3158EAI RS-485/RS-422 transceiver with isolation, 250 kbps data rate, 5 V supply, -40°C to 85°C.
