TRS3227IDBR 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; it goes high when V- falls below -3.5 V and the device is ready to transmit. |
| 2 | C1+ | passive | Positive terminal of the voltage-doubler charge-pump capacitor. |
| 3 | V+ | power_out | +2 × VCC supply 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 | -2 × VCC supply generated by the charge pump. |
| 8 | RIN | input | RS-232 receiver input, rated -25 V to 25 V per the recommended operating conditions. |
| 9 | ROUT | output | CMOS receiver output. |
| 10 | INVALID | output | Valid-signal detector output, active low; a logic high indicates a valid RS-232 level is present on a receiver input. |
| 11 | DIN | input | CMOS driver input; VIH is 2 V minimum at VCC = 3.3 V or 2.4 V minimum at VCC = 5 V, and VIL is 0.8 V maximum. |
| 12 | FORCEON | input | Force-on input, active high; driving it high overrides powerdown and keeps drivers and receivers on, with FORCEOFF required to be high. |
| 13 | DOUT | output | RS-232 driver output; the short-circuit duration to GND is unlimited. |
| 14 | GND | power_in | Ground reference for the device. |
| 15 | VCC | power_in | Single-supply input, 3 V to 5.5 V. |
| 16 | FORCEOFF | input | Force-off input, active low; driving it low shuts down drivers, receivers and the charge pump, overriding auto-powerdown and FORCEON. |
