TRS3386ECPWR from Texas Instruments, in a TSSOP-20. 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 terminal of voltage-doubler charge-pump capacitor for external 0.1 to 0.33 μF capacitor. |
| 2 | V+ | power_out | Positive charge-pump supply output nominally 5.5 V for RS-232 driver circuit. |
| 3 | C1− | passive | Negative terminal of voltage-doubler charge-pump capacitor. |
| 4 | C2+ | passive | Positive terminal of inverting charge-pump capacitor for external 0.1 to 0.33 μF capacitor. |
| 5 | C2− | passive | Negative terminal of inverting charge-pump capacitor. |
| 6 | V− | power_out | Negative charge-pump supply output nominally −5.5 V for RS-232 driver circuit. |
| 7 | DIN1 | input | Driver input for TTL/CMOS logic levels referenced to VL with 0.5 V hysteresis. |
| 8 | DIN2 | input | Driver input for TTL/CMOS logic levels referenced to VL with 0.5 V hysteresis. |
| 9 | DIN3 | input | Driver input for TTL/CMOS logic levels referenced to VL with 0.5 V hysteresis. |
| 10 | ROUT2 | output | Receiver output swinging from 0 to VL with maximum 0.15 μs propagation delay. |
| 11 | ROUT1 | output | Receiver output swinging from 0 to VL with maximum 0.15 μs propagation delay. |
| 12 | VL | power_in | Logic supply input from 2.25 V to VCC for all CMOS inputs and outputs. |
| 13 | RIN2 | input | RS-232 receiver input accepting ±25 V with 3 to 7 kΩ input resistance. |
| 14 | RIN1 | input | RS-232 receiver input accepting ±25 V with 3 to 7 kΩ input resistance. |
| 15 | DOUT3 | output | RS-232 driver output swinging ±5.4 V typical with 0.15 μs skew on 3 kΩ load. |
| 16 | DOUT2 | output | RS-232 driver output swinging ±5.4 V typical with 0.15 μs skew on 3 kΩ load. |
| 17 | DOUT1 | output | RS-232 driver output swinging ±5.4 V typical with 0.15 μs skew on 3 kΩ load. |
| 18 | GND | power_in | Ground reference for all signal and supply voltages. |
| 19 | VCC | power_in | Supply voltage input from 3 V to 5.5 V for charge pump and logic circuits. |
| 20 | PWRDWN | input | Powerdown control input; logic low enables 1 μA shutdown mode, high enables normal 0.3 to 1 mA operation. |
