SP3232EEN

SP3232EEN is the UMW (UTD Semiconductor) RS-232 transceiver in SOP-16, written word-for-word in the ordering information of the UMW datasheet. UMW publishes no lifecycle grading for the part; the code stands in the maker’s current datasheet ordering table. Every figure on this page is UMW’s own: a supply of 3.0 V to 3.6 V or 4.5 V to 5.5 V, a data rate of 235 kbps typical and 120 kbps minimum, supply current of 1 mA typical and 3 mA maximum, a driver high output of +5.0 V minimum and +5.4 V typical, over −40 °C to +105 °C, with two drivers and two receivers. The selection point is a second-source, 3.3 V-capable serial port whose wide temperature grade suits industrial enclosures, in the standard 16-pin wide body. Selection advice: the SP3232E designation originates with MaxLinear, whose device carries a different datasheet; UMW’s supply-current and data-rate figures above are UMW’s, so qualify this code against the UMW document and state the maker in the RFQ. Parameters verified against the UMW SP3232EEN datasheet (ordering information and electrical characteristics).
