SP3232EEY-L

MaxLinear · RS232 ICs · TSSOP-16

SP3232EEY-L from MaxLinear, in a TSSOP-16. Pinout and pin descriptions extracted from the datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 C1+ passive Positive terminal of the voltage-doubler charge-pump flying capacitor (0.1uF typ to C1-).
2 V+ power_out +5.5V charge-pump output rail. Bypass to GND (or VCC) with a 0.1uF capacitor.
3 C1- passive Negative terminal of the voltage-doubler charge-pump flying capacitor.
4 C2+ passive Positive terminal of the inverting charge-pump flying capacitor (0.1uF typ to C2-).
5 C2- passive Negative terminal of the inverting charge-pump flying capacitor.
6 V- power_out -5.5V charge-pump output rail. Bypass to GND (or VCC) with a 0.1uF capacitor.
7 T2OUT output RS-232 driver #2 output (typ +/-5.4V swing into 3kOhm load). Short-circuit protected (+/-60mA).
8 R2IN input RS-232 receiver #2 input. Accepts +/-15V (abs max +/-25V) with typical 5kOhm input resistance and hysteresis of ~0.3V.
9 R2OUT output TTL/CMOS receiver #2 output (rail-to-rail on VCC).
10 T2IN input TTL/CMOS driver #2 input. Logic thresholds: VIL <= 0.8V, VIH >= 2.0V (VCC=3.3V) or 2.4V (VCC=5.0V).
11 T1IN input TTL/CMOS driver #1 input. Logic thresholds: VIL <= 0.8V, VIH >= 2.0V (VCC=3.3V) or 2.4V (VCC=5.0V).
12 R1OUT output TTL/CMOS receiver #1 output (rail-to-rail on VCC).
13 R1IN input RS-232 receiver #1 input. Accepts +/-15V (abs max +/-25V) with typical 5kOhm input resistance and hysteresis of ~0.3V.
14 T1OUT output RS-232 driver #1 output (typ +/-5.4V swing into 3kOhm load). Short-circuit protected (+/-60mA).
15 GND power_in Device ground reference.
16 VCC power_in Positive supply, 3.0V to 5.5V. Bypass to GND with a 0.1uF capacitor. Typ ICC = 0.3mA (no load, VCC=3.3V).

CAD (KiCad official)

  • Symbol: SP3232EEY-L
  • Footprint: Package_SO:TSSOP-16_4.4x5mm_P0.65mm
  • 3D model: TSSOP-16 (KiCad packages3D, STEP)
  • 3D model files: sp3232eey-l-etched.step / sp3232eey-l-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sp3232eey-l.step / sp3232eey-l.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
sp3232eey-l.step 205 KB You want the bare part, or you mark your own boards.
sp3232eey-l-etched.step 2.5 MB You want the part with SP3232EEY-L already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 631 faces against 255 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: MaxLinear datasheet (21 pp, sha256 657cf6a156b351de, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
