SP3485EEN

SP3485EEN is the SOP-8 tape-and-reel ordering code for the UMW (UTD Semiconductor) SP3485E low-power RS-485 transceiver, listed word-for-word in the ordering information of the UMW datasheet (June 2025 revision) as UMW SP3485EEN, 2,500 pieces per reel. UMW publishes no lifecycle grading system; the code is current in that datasheet. On a 3.0 V to 3.6 V supply the driver delivers a differential output of at least 1.5 V into a 54 Ω load with ±250 mA short-circuit current, the receiver thresholds are +200 mV maximum and -200 mV minimum over a -7 V to +12 V common-mode range with 96 kΩ typical input resistance, and supply current is 520 µA typical and 800 µA maximum; the datasheet electrical table rates the maximum data rate at 10 Mbps, and the 12 Mbps figure in its feature list is not the electrical-table value, so 10 Mbps is the figure used here. The selection point is a native 3.3 V RS-485 node in metering, building control and industrial serial links. Selection advice: UMW documents its own figures for this code, which differ from other vendors’ same-name SP3485 parts - qualify against the UMW datasheet, and quote the full SP3485EEN code, since UMW also lists a TSSOP-8 sibling (SP3485EET) that does not fit SOP-8 layouts. Parameters verified against the UMW SP3485E datasheet (ordering information and electrical characteristics).
