SP3220EUEY-L from MaxLinear, in a TSSOP-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 | EN | input | Receiver enable: logic LOW for normal operation, logic HIGH disables the receiver outputs (high-Z state). |
| 2 | C1+ | passive | Positive terminal of the voltage doubler charge-pump capacitor. |
| 3 | V+ | power_out | +5.5V output generated by the charge pump. |
| 4 | C1- | passive | Negative terminal of the voltage doubler charge-pump capacitor. |
| 5 | C2+ | passive | Positive terminal of the inverting charge-pump capacitor. |
| 6 | C2- | passive | Negative terminal of the inverting charge-pump capacitor. |
| 7 | V- | power_out | -5.5V output generated by the charge pump. |
| 8 | R1IN | input | RS-232 receiver input with internal 5kΩ pull-down, input voltage range ±15V. |
| 9 | R1OUT | output | TTL/CMOS receiver output. |
| 10 | N.C. | unconnected | No connect. |
| 11 | T1IN | input | TTL/CMOS driver input, no internal pull-up so unused input should be tied to VCC or GND. |
| 12 | N.C. | unconnected | No connect. |
| 13 | T1OUT | output | RS-232 driver output. |
| 14 | GND | power_in | Ground. |
| 15 | VCC | power_in | +3.0V to +5.5V supply voltage. |
| 16 | SHDN | input | Shutdown control input: drive HIGH for normal operation, drive LOW to shut down the driver (high-Z output) and on-board power supply. |
