SP3232EEN

UMW · RS232 ICs · SOP-16

SP3232EEN from UMW, in a SOP-16. Pinout and pin descriptions extracted from the manufacturer 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 C1. Connect an external ceramic capacitor between C1+ and C1- (typ. 0.1 µF at 3.3V, 0.047 µF at 5V per Table 1).
2 V+ power_out Regulated +5.5V output generated by the voltage-doubler charge pump. Bypass to GND with a ceramic capacitor C3 (typ. 0.1 µF to 0.33 µF per Table 1). Absolute max range -0.3V to +7.0V.
3 C1- passive Negative terminal of the voltage-doubler charge-pump flying capacitor C1.
4 C2+ passive Positive terminal of the inverting charge-pump flying capacitor C2. Connect an external ceramic capacitor between C2+ and C2-.
5 C2- passive Negative terminal of the inverting charge-pump flying capacitor C2.
6 V- power_out Regulated -5.5V output generated by the inverting charge pump. Bypass to GND with a ceramic capacitor C4 (typ. 0.1 µF to 0.33 µF per Table 1). Absolute max range +0.3V to -7.0V.
7 DOUT2 output RS-232 driver output for channel 2. Swings between V- and V+ (typ. ±5.4V into 3kΩ). Short-circuit current limited to ±60 mA max. Absolute max output range -13.2V to +13.2V.
8 RIN2 input RS-232 receiver input for channel 2. Accepts ±25V line levels; internal 5kΩ (typ.) pull-down to GND. Positive-going threshold typ. 1.5V, negative-going typ. 1.2V (VCC=3.3V).
9 ROUT2 output TTL/CMOS receiver output for channel 2. VOH typ. VCC-0.1V at IOH=-1.0 mA; VOL max 0.4V at IOL=1.6 mA.
10 DIN2 input TTL/CMOS driver input for channel 2. VIH min 2.0V (VCC=3.3V) / 2.4V (VCC=5.5V); VIL max 0.8V. Accepts 5.0V logic with 3.3V supply. Absolute max input 6.0V.
11 DIN1 input TTL/CMOS driver input for channel 1. VIH min 2.0V (VCC=3.3V) / 2.4V (VCC=5.5V); VIL max 0.8V. Accepts 5.0V logic with 3.3V supply.
12 ROUT1 output TTL/CMOS receiver output for channel 1. VOH typ. VCC-0.1V at IOH=-1.0 mA; VOL max 0.4V at IOL=1.6 mA.
13 RIN1 input RS-232 receiver input for channel 1. Accepts ±25V line levels; internal 5kΩ (typ.) pull-down to GND. Positive-going threshold typ. 1.5V, negative-going typ. 1.2V (VCC=3.3V).
14 DOUT1 output RS-232 driver output for channel 1. Swings between V- and V+ (typ. ±5.4V into 3kΩ). Short-circuit current limited to ±60 mA max.
15 GND power_in Device ground reference. All voltages are specified with respect to network GND.
16 VCC power_in Positive supply, +3.0V to +5.5V. Typical supply current 1 mA (no load, VCC=3.3V), 3 mA max. Bypass to GND with a ceramic capacitor CBYPASS (typ. 0.1 µF, see Table 1).

Provenance

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

  • Datasheet: UMW datasheet (11 pp, sha256 053c1ca2d27a6dfd, 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).
