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. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SSOP-16-208mil |+| Category | Interface |+| Pins | 16 |++## CAD (KiCad official)++- Symbol: `TRS3227IDBR`+- Footprint: `Package_SO:SSOP-16_5.3x6.2mm_P0.65mm`+- 3D model: SSOP-16-208mil (KiCad packages3D, STEP)+- 3D model files: `trs3227idbr-etched.step` / `trs3227idbr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `trs3227idbr.step` / `trs3227idbr.glb` are the bare package body.++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/cn/lit/gpn/trs3227) (17 pp, sha256 `c8b02be4447a0305`, retrieved 2026-10-08, tier: lcsc)+- **Extractor:** parts-factory `2.0.0` / `extract_pins 0.3`, primary `claude-haiku-5-5` (text), consensus `claude-sonnet-5-5` (agreed), guards: pin_guards 0.1: passed.
