SN65C3232DWR

Texas Instruments · RS232 ICs · SOIC-16-300mil

SN65C3232DWR 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.
2 V+ power_out Positive charge-pump output for the storage capacitor only; the datasheet gives no load or current rating for this pin.
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; the datasheet gives no load or current rating for this pin.
7 DOUT2 output RS-232 line data output to the remote RS-232 system; the driver output is protected against shorts to ground and rated at ±13.2 V maximum output voltage.
8 RIN2 input RS-232 line data input from the remote RS-232 system; receiver input range is ±25 V.
9 ROUT2 output Logic data output to the UART; receiver output is VCC-referenced (VOH of VCC-0.6 V to VCC-0.1 V at IOH = -1 mA).
10 DIN2 input Logic data input from the UART; driver input range is 0 V to 5.5 V with VIL of 0.8 V maximum and VIH of 2.4 V (VCC = 5 V) or 2 V (VCC = 3.3 V).
11 DIN1 input Logic data input from the UART; driver input range is 0 V to 5.5 V with VIL of 0.8 V maximum and VIH of 2.4 V (VCC = 5 V) or 2 V (VCC = 3.3 V).
12 ROUT1 output Logic data output to the UART; receiver output is VCC-referenced (VOH of VCC-0.6 V to VCC-0.1 V at IOH = -1 mA).
13 RIN1 input RS-232 line data input from the remote RS-232 system; receiver input range is ±25 V.
14 DOUT1 output RS-232 line data output to the remote RS-232 system; the driver output is protected against shorts to ground and rated at ±13.2 V maximum output voltage.
15 GND power_in Ground reference for the device; all voltages are referenced to network GND.
16 VCC power_in Supply voltage, to be connected to an external 3 V to 5.5 V power supply.
