SP3232EEN-MS from MSKSEMI, in a SOP-16. 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 for the first charge pump capacitor (C1) of the dual charge pump. |
| 2 | V+ | power_out | Doubled voltage terminal generated by the charge pump; absolute limit is VCC-0.3 to +7 V, and it needs its storage capacitor (C3) connected. |
| 3 | C1- | passive | Negative terminal for the first charge pump capacitor (C1) of the dual charge pump. |
| 4 | C2+ | passive | Positive terminal for the second charge pump capacitor (C2) of the dual charge pump. |
| 5 | C2- | passive | Negative terminal for the second charge pump capacitor (C2) of the dual charge pump. |
| 6 | V- | power_out | Inverted voltage terminal generated by the charge pump; absolute limit is +0.3 to -7 V, and it needs its storage capacitor (C4) connected. |
| 7 | T2OUT | output | Second RS-232 transmitter output, with an absolute range of ±13.2 V and a ±5 V minimum swing into a 3 kΩ load. |
| 8 | R2IN | input | Second RS-232 receiver input, rated for a ±25 V input range with about 5 kΩ input impedance. |
| 9 | R2OUT | output | Second receiver CMOS output, limited to -0.3 V to VCC+0.3 V. |
| 10 | T2IN | input | Second transmitter TTL/CMOS logic input with 2 V minimum high threshold and 0.8 V maximum low threshold; no internal pull-up, so unused input may tie to GND or VCC. |
| 11 | T1IN | input | First transmitter TTL/CMOS logic input with 2 V minimum high threshold and 0.8 V maximum low threshold; no internal pull-up, so unused input may tie to GND or VCC. |
| 12 | R1OUT | output | First receiver CMOS output, limited to -0.3 V to VCC+0.3 V. |
| 13 | R1IN | input | First RS-232 receiver input, rated for a ±25 V input range with about 5 kΩ input impedance. |
| 14 | T1OUT | output | First RS-232 transmitter output, with an absolute range of ±13.2 V and a ±5 V minimum swing into a 3 kΩ load. |
| 15 | GND | power_in | Ground reference for all voltages on the device. |
| 16 | VCC | power_in | Supply voltage input; absolute limit is -0.3 to +6 V, with 3 V to 5.5 V operating range. |
