TRSF3232EIDBR

Texas Instruments · RS232 ICs · SSOP-16-208mil

TRSF3232EIDBR 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 C1+ passive Positive lead of the C1 charge-pump capacitor, connected to an external 0.1 µF (3.3 V) or 0.047 µF (5 V) capacitor.
2 V+ power_out Positive charge pump output for the storage capacitor only; do not use as a supply for other circuits.
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 V- power_out Negative charge pump output for the storage capacitor only; do not use as a supply for other circuits.
7 DOUT2 output RS-232 line data output to the remote RS-232 system; ESD protected to ±15 kV (HBM and IEC 61000-4-2 air-gap), ±8 kV (IEC contact).
8 RIN2 input RS-232 line data input from the remote RS-232 system; receiver input range is −25 V to 25 V.
9 ROUT2 output Logic data output to the UART.
10 DIN2 input Logic data input from the UART; driver input range is 0 V to 5.5 V.
11 DIN1 input Logic data input from the UART; driver input range is 0 V to 5.5 V.
12 ROUT1 output Logic data output to the UART.
13 RIN1 input RS-232 line data input from the remote RS-232 system; receiver input range is −25 V to 25 V.
14 DOUT1 output RS-232 line data output to the remote RS-232 system; ESD protected to ±15 kV (HBM and IEC 61000-4-2 air-gap), ±8 kV (IEC contact).
15 GND power_in Ground reference for the device (printed as “GRD” in the pin table).
16 VCC power_in Supply voltage; connect to an external 3 V to 5.5 V power supply.
