TRS232EIDWR from Texas Instruments, in a SOIC-16-300mil. 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 | C1+ | passive | Positive lead of the C1 charge-pump capacitor, which is connected between C1+ and C1− (1 µF in the typical circuit). |
| 2 | VS+ | power_out | Positive charge-pump output for the storage capacitor only; the datasheet gives an absolute maximum of VCC − 0.3 V to 15 V. |
| 3 | C1- | passive | Negative lead of the C1 charge-pump capacitor. |
| 4 | C2+ | passive | Positive lead of the C2 charge-pump capacitor. |
| 5 | C2- | passive | Negative lead of the C2 charge-pump capacitor. |
| 6 | VS- | power_out | Negative charge-pump output for the storage capacitor only; the datasheet gives an absolute range of −0.3 V to −15 V. |
| 7 | DOUT2 | output | RS-232 line data output to the remote RS-232 system; the absolute output range is VS− − 0.3 V to VS+ + 0.3 V. |
| 8 | RIN2 | input | RS-232 line data input from the remote RS-232 system, which accepts ±30 V. |
| 9 | ROUT2 | output | Logic data output to the UART; VOH is at least 3.5 V at IOH = −1 mA, and the absolute range is −0.3 V to VCC + 0.3 V. |
| 10 | DIN2 | input | Logic data input from the UART; VIH is 2 V minimum and VIL is 0.8 V maximum. |
| 11 | DIN1 | input | Logic data input from the UART; VIH is 2 V minimum and VIL is 0.8 V maximum. |
| 12 | ROUT1 | output | Logic data output to the UART; VOH is at least 3.5 V at IOH = −1 mA, and the absolute range is −0.3 V to VCC + 0.3 V. |
| 13 | RIN1 | input | RS-232 line data input from the remote RS-232 system, which accepts ±30 V. |
| 14 | DOUT1 | output | RS-232 line data output to the remote RS-232 system; the absolute output range is VS− − 0.3 V to VS+ + 0.3 V. |
| 15 | GND | power_in | Ground reference; all device voltages are referenced to network GND. |
| 16 | VCC | power_in | Supply voltage input, connected to an external 5 V supply; recommended range is 4.5 V to 5.5 V (5 V nominal). |
