TRS3386EIPWR

Texas Instruments · RS232 ICs · TSSOP-20

TRS3386EIPWR 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 the voltage-doubler charge-pump capacitor
2 V+ power_out 5.5-V supply generated by the charge pump
3 C1− passive Negative terminal of the voltage-doubler charge-pump capacitor
4 C2+ passive Positive terminal of the inverting charge-pump capacitor
5 C2− passive Negative terminal of the inverting charge-pump capacitor
6 V− power_out -5.5-V supply generated by the charge pump
7 DIN1 input Driver input
8 DIN2 input Driver input
9 DIN3 input Driver input
10 ROUT2 output Receiver output; swings between 0 and VL
11 ROUT1 output Receiver output; swings between 0 and VL
12 VL power_in Logic-level supply; all CMOS inputs and outputs are referenced to this supply
13 RIN2 input RS-232 receiver input
14 RIN1 input RS-232 receiver input
15 DOUT3 output RS-232 driver output
16 DOUT2 output RS-232 driver output
17 DOUT1 output RS-232 driver output
18 GND power_in Ground
19 VCC power_in 3-V to 5.5-V supply voltage
20 PWRDWN input Powerdown input; L = powerdown, H = normal operation

CAD (KiCad official)

  • Symbol: TRS3386EIPWR
  • Footprint: Package_SO:TSSOP-20_4.4x6.5mm_P0.65mm
  • 3D model: TSSOP-20 (KiCad packages3D, STEP)
  • 3D model files: trs3386eipwr-etched.step / trs3386eipwr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); trs3386eipwr.step / trs3386eipwr.glb are the bare package body.
