MaxLinear · Pre-ordered Chips · SSOP-20-208mil
SP3222ECA-L from MaxLinear, in a SSOP-20-208mil. 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 | EN | input | Receiver enable; apply logic LOW for normal operation and logic HIGH to disable 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 | T2OUT | output | RS-232 driver output. |
| 9 | R2IN | input | RS-232 receiver input, specified for an input voltage range of -15V to 15V. |
| 10 | R2OUT | output | TTL/CMOS receiver output, tri-stated when EN is HIGH. |
| 11 | N.C. | unconnected | No connect. |
| 12 | T2IN | input | TTL/CMOS driver input; the driver input has no pull-up, so unused inputs should be connected to VCC or GND. |
| 13 | T1IN | input | TTL/CMOS driver input; the driver input has no pull-up, so unused inputs should be connected to VCC or GND. |
| 14 | N.C. | unconnected | No connect. |
| 15 | R1OUT | output | TTL/CMOS receiver output, tri-stated when EN is HIGH. |
| 16 | R1IN | input | RS-232 receiver input, specified for an input voltage range of -15V to 15V. |
| 17 | T1OUT | output | RS-232 driver output, protected against infinite short-circuit to ground. |
| 18 | GND | power_in | Ground. |
| 19 | VCC | power_in | Supply voltage, 3.0V to 5.5V. |
| 20 | SHDN | input | Shutdown control input; drive HIGH for normal operation and LOW to shut down the drivers (high-Z output) and the on-board power supply. |
