SN65C3232EDWR

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

SN65C3232EDWR 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 storage capacitor only (absolute max -0.3 V to 7 V).
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 storage capacitor only (absolute max -7 V).
7 DOUT2 output RS232 line data output to the remote RS232 system, with ±15 kV HBM and IEC 61000-4-2 air-gap ESD protection (±8 kV contact).
8 RIN2 input RS232 line data input from the remote RS232 system, with ±25 V input range, 5 kΩ typical internal load and ±15 kV HBM ESD protection.
9 ROUT2 output Logic data output to the UART; goes high when RIN2 is open.
10 DIN2 input Logic data input from the UART; must be connected to a valid high or low level (VIL max 0.8 V).
11 DIN1 input Logic data input from the UART; must be connected to a valid high or low level (VIL max 0.8 V).
12 ROUT1 output Logic data output to the UART; goes high when RIN1 is open.
13 RIN1 input RS232 line data input from the remote RS232 system, with ±25 V input range, 5 kΩ typical internal load and ±15 kV HBM ESD protection.
14 DOUT1 output RS232 line data output to the remote RS232 system, with ±15 kV HBM and IEC 61000-4-2 air-gap ESD protection (±8 kV contact).
15 GND power_in Ground.
16 VCC power_in Supply voltage, connect to an external 3-V to 5.5-V power supply.
