SN65C3232DR

Texas Instruments · RS232 ICs · SOIC-16

SN65C3232DR from Texas Instruments, in a SOIC-16. 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; connect the external 0.1 µF capacitor between C1+ and C1-.
2 V+ power_out Positive charge-pump output for the storage capacitor only; it is not intended as a load supply.
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; it is not intended as a load supply.
7 DOUT2 output RS-232 line data output to the remote RS-232 system.
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.
15 GND power_in Ground reference for the device.
16 VCC power_in Supply voltage; connect to an external 3-V to 5.5-V power supply.
