SN65C3232EDR

Texas Instruments · RS232 ICs · SOIC-16

SN65C3232EDR 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.
2 V+ power_out Positive charge pump output for storage capacitor only; absolute maximum -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 maximum range is 0.3 V to -7 V.
7 DOUT2 output RS232 line data output (to remote RS232 system) with ±15 kV HBM and ±15 kV IEC air-gap ESD protection.
8 RIN2 input RS232 line data input (from remote RS232 system) with ±15 kV HBM ESD protection and input range of -25 V to 25 V.
9 ROUT2 output Logic data output (to UART).
10 DIN2 input Logic data input (from UART); accepts 5-V logic with 3.3-V supply, absolute maximum -0.3 V to 6 V.
11 DIN1 input Logic data input (from UART); accepts 5-V logic with 3.3-V supply, absolute maximum -0.3 V to 6 V.
12 ROUT1 output Logic data output (to UART).
13 RIN1 input RS232 line data input (from remote RS232 system) with ±15 kV HBM ESD protection and input range of -25 V to 25 V.
14 DOUT1 output RS232 line data output (to remote RS232 system) with ±15 kV HBM and ±15 kV IEC air-gap ESD protection.
15 GND power_in Ground.
16 VCC power_in Supply voltage, connect to external 3-V to 5.5-V power supply; a minimum 1-µF capacitor to GND is needed for the IEC ESD level.
