SP3232EEY-L/TR

SP3232EEY-L/TR is the tape-and-reel ordering code for the MaxLinear SP3232E RS-232 transceiver in a 16-pin TSSOP package, listed in the ordering information of the official SP3232E datasheet (the tube code is SP3232EEY-L). The device integrates two drivers and two receivers, runs from a single 3.0 V to 5.5 V supply with four 0.1 µF charge-pump capacitors, meets TIA/EIA-232-F and ITU V.28, and guarantees a 235 kbps data rate across the -40 °C to +85 °C industrial range. The E grade is the enhanced-ESD version: the RS-232 pins are protected to ±15 kV HBM, which is the failure point that kills unprotected serial ports on field cabling, docking connectors and service interfaces. Selection advice: pick the EY TSSOP code when board area matters and the EEN SOIC code when the layout already exists in SOIC-16; for data rates above 235 kbps step up to the SP3232EH family (up to 460 kbps), and note that the pinout follows the industry-standard 3232 footprint, so this part is a second-source option against TI MAX3232E designs (also listed) — re-verify the capacitor values and ESD grade against your schematic before substituting.
