SP3232ECA-L from MaxLinear, in a SSOP-16-208mil. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | C1+ | passive | Positive terminal of the voltage doubler charge-pump capacitor; the datasheet specifies external capacitors as low as 0.1µF with a 16V breakdown rating. |
| 2 | V+ | power_out | Regulated 5.5V output generated by the charge pump, regardless of VCC over the 3.0V to 5.5V range. |
| 3 | C1- | passive | Negative terminal of the voltage doubler charge-pump capacitor. |
| 4 | C2+ | passive | Positive terminal of the inverting charge-pump capacitor. |
| 5 | C2- | passive | Negative terminal of the inverting charge-pump capacitor. |
| 6 | V- | power_out | Regulated -5.5V output generated by the charge pump, regardless of VCC over the 3.0V to 5.5V range. |
| 7 | T2OUT | output | RS-232 driver output, protected against infinite short-circuits to ground and meeting ±5V minimum when fully loaded. |
| 8 | R2IN | input | RS-232 receiver input with RxIN absolute maximum of ±25V and an internal 5kΩ pulldown that forces the output HIGH when left unconnected. |
| 9 | R2OUT | output | TTL/CMOS receiver output, limited to -0.3V to (VCC + 0.3V). |
| 10 | T2IN | input | TTL/CMOS driver input, limited to -0.3V to (VCC + 0.3V); it has no pull-up, so unused inputs should be tied to VCC or GND. |
| 11 | T1IN | input | TTL/CMOS driver input, limited to -0.3V to (VCC + 0.3V); it has no pull-up, so unused inputs should be tied to VCC or GND. |
| 12 | R1OUT | output | TTL/CMOS receiver output, limited to -0.3V to (VCC + 0.3V). |
| 13 | R1IN | input | RS-232 receiver input with RxIN absolute maximum of ±25V and an internal 5kΩ pulldown that forces the output HIGH when left unconnected. |
| 14 | T1OUT | output | RS-232 driver output, protected against infinite short-circuits to ground and meeting ±5V minimum when fully loaded. |
| 15 | GND | power_in | Ground reference for the device. |
| 16 | VCC | power_in | Supply voltage, 3.0V to 5.5V. |
