TRS3227EIDBR 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 | Output active high when V- ≤ -3.5 V indicating device ready to transmit. |
| 2 | C1+ | passive | Positive terminal of voltage-doubler charge-pump capacitor, 0.1 μF recommended. |
| 3 | V+ | power_out | Charge pump positive output (+2 × VCC, -0.3 to 7 V), powers RS-232 drivers. |
| 4 | C1− | passive | Negative terminal of voltage-doubler charge-pump capacitor, 0.1 μF recommended. |
| 5 | C2+ | passive | Positive terminal of inverting charge-pump capacitor, 0.1 μF recommended. |
| 6 | C2− | passive | Negative terminal of inverting charge-pump capacitor, 0.1 μF recommended. |
| 7 | V− | power_out | Charge pump negative output (-2 × VCC, -7 to 0.3 V), powers RS-232 drivers. |
| 8 | RIN | input | RS-232 receiver input (-25 to 25 V) with ±15 kV IEC ESD protection. |
| 9 | ROUT | output | CMOS receiver output (VOH = VCC - 0.6 V, VOL = 0.4 V, 150 ns propagation delay). |
| 10 | INVALID | output | Valid signal detector output, active low for indeterminate input (±0.3 V threshold, 0.5 V hysteresis). |
| 11 | DIN | input | CMOS driver input (VIH ≥ 2 V, VIL ≤ 0.8 V at 3.3 V), tri-state when FORCEOFF low. |
| 12 | FORCEON | input | Force-on input, active high to override powerdown (requires FORCEOFF high). |
| 13 | DOUT | output | RS-232 driver output (±5.4 V, 1 Mbit/s) with ±15 kV ESD protection, tri-state when FORCEOFF low. |
| 14 | GND | power_in | Ground reference with ±15 kV IEC ESD protection to all I/O pins. |
| 15 | VCC | power_in | Supply input (3-5.5 V, 2 mA max quiescent, 1 μA with auto-powerdown enabled). |
| 16 | FORCEOFF | input | Force-off input, active low to disable drivers, receivers, and charge pump. |
