MAX3227IDBR from Texas Instruments, 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 | READY | output | Ready to transmit output, active high when V- goes below -3.5 V and charge pump regulates. |
| 2 | C1+ | passive | Positive terminal of voltage-doubler charge-pump capacitor (0.1 µF at 3.3 V, 0.047 µF at 5 V). |
| 3 | V+ | power_out | Positive supply voltage +2 × VCC generated by charge pump with absolute maximum range -0.3 V to 7 V. |
| 4 | C1− | passive | Negative terminal of voltage-doubler charge-pump capacitor (0.1 µF nominal). |
| 5 | C2+ | passive | Positive terminal of inverting charge-pump capacitor (0.1 µF at 3.3 V, 0.33 µF at 5 V). |
| 6 | C2− | passive | Negative terminal of inverting charge-pump capacitor (0.1 µF at 3.3 V, 0.47 µF at 5 V). |
| 7 | V− | power_out | Negative supply voltage -2 × VCC generated by charge pump with absolute maximum range 0.3 V to -7 V. |
| 8 | RIN | input | RS-232 receiver input with ±25 V voltage range and ±15 kV ESD protection (human-body model). |
| 9 | ROUT | output | CMOS receiver output with VOH = VCC - 0.1 V (IOH = -1 mA) and VOL = 0.4 V (IOL = 1.6 mA). |
| 10 | INVALID | output | Valid signal detector output, active low when RS-232 receiver input is outside the ±2.7 V valid region. |
| 11 | DIN | input | CMOS driver input with logic thresholds VIL = 0 to 0.8 V and VIH = 2 V to VCC minimum. |
| 12 | FORCEON | input | Force-on input, active high (2 V to VCC), to keep drivers and receivers active when FORCEOFF is high. |
| 13 | DOUT | output | RS-232 driver output with voltage range ±5 V to ±5.4 V (3 kΩ load) and 24 to 150 V/µs slew rate. |
| 14 | GND | power_in | Ground reference for all power supplies and signal paths. |
| 15 | VCC | power_in | Single-supply voltage input, 3 V to 5.5 V recommended operating range with -40 to 85°C operating temperature. |
| 16 | FORCEOFF | input | Force-off input, active low (0 to 0.8 V), to shut down drivers, receivers, and charge pump. |
