It handles 2.5 Mbps data rate on a 5 V ±5% rail (4.75 V to 5.25 V), and comes in a 16-pin SOIC (0.154\" body width) for surface-mount assembly. The commercial temperature range (0°C to 70°C) suits it for indoor equipment like PLCs, building-automation controllers, and test gear that stays above freezing. ## Supply rail and data rate — the so-what The 4.75 V to 5.25 V supply means this driver expects a regulated 5 V bus, not a 3.3 V rail. If your board runs 3.3 V logic, you will need a level translator or a separate 5 V supply for the driver side. At 2.5 Mbps, the part can drive a few hundred feet of twisted-pair cable with proper termination — enough for most factory-floor serial links, but not the multi-megabit backplane speeds some newer transceivers offer. ## Package and mounting — field-fit check Housed in a 16-SOIC (0.154\" width, 3.90 mm body), surface-mount only. No DIP option, so a socketed field swap means having a SOIC footprint on the board. The tube shipment (not tape-and-reel) is typical for engineering quantities; if you are feeding a pick-and-place line, confirm the reel-pack variant or plan to transfer from tube. ## Lifecycle and compliance ROHS3 compliant, so it clears the current EU restriction list without an exemption. No lead (Pb) finish concern for RoHS-driven BOMs.","metaTitle":"MAX3044CSE+ RS-422/RS-485 Driver, 2.5 Mbps, 16-SOIC","metaDescription":"MAX3044CSE+ is a 4/0 RS-422/RS-485 line driver in 16-SOIC, 2.5 Mbps, 4.75V–5.25V supply, 0°C–70°C.
