Texas Instruments · RS232 ICs · TSSOP-16

SN65C3232EPWR from Texas Instruments, in a TSSOP-16. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 C1+ passive Positive terminal of charge-pump flying capacitor C1; external capacitor value is 0.1 µF at VCC = 3.3 V or 0.047 µF at VCC = 5 V.
2 V+ power_out Positive charge-pump output for external storage capacitor only; absolute maximum +7 V with respect to GND.
3 C1- passive Negative terminal of charge-pump flying capacitor C1; paired with C1+ for the doubling stage.
4 C2+ passive Positive terminal of charge-pump flying capacitor C2; external capacitor value is 0.1 µF at VCC = 3.3 V or 0.33 µF at VCC = 5 V.
5 C2- passive Negative terminal of charge-pump flying capacitor C2; paired with C2+ for the inverting stage.
6 V- power_out Negative charge-pump output for external storage capacitor only; absolute maximum −7 V with respect to GND.
7 DOUT2 output RS-232 channel 2 line driver output to remote RS-232 system; ±15-kV HBM and ±15-kV IEC 61000-4-2 air-gap ESD protected; VOH ≥ +5 V, VOL ≤ −5 V into 3 kΩ.
8 RIN2 input RS-232 channel 2 line receiver input from remote RS-232 system; ±15-kV HBM and ±15-kV IEC 61000-4-2 ESD protected; input range ±25 V, internal 3-7 kΩ load.
9 ROUT2 output Logic-level receiver channel 2 output to UART; output is high when RIN2 is open or driver is off; VOH ≥ VCC − 0.6 V at IOH = −1 mA.
10 DIN2 input Logic-level driver channel 2 input from UART; VIH ≥ 2 V (VCC = 3.3 V) or ≥ 2.4 V (VCC = 5 V); VIL ≤ 0.8 V; input range 0 to 5.5 V.
11 DIN1 input Logic-level driver channel 1 input from UART; VIH ≥ 2 V (VCC = 3.3 V) or ≥ 2.4 V (VCC = 5 V); VIL ≤ 0.8 V; input range 0 to 5.5 V.
12 ROUT1 output Logic-level receiver channel 1 output to UART; output is high when RIN1 is open or driver is off; VOH ≥ VCC − 0.6 V at IOH = −1 mA.
13 RIN1 input RS-232 channel 1 line receiver input from remote RS-232 system; ±15-kV HBM and ±15-kV IEC 61000-4-2 ESD protected; input range ±25 V, internal 3-7 kΩ load.
14 DOUT1 output RS-232 channel 1 line driver output to remote RS-232 system; ±15-kV HBM and ±15-kV IEC 61000-4-2 air-gap ESD protected; VOH ≥ +5 V, VOL ≤ −5 V into 3 kΩ.
15 GND power_in Ground reference for all voltages; included in pin-to-pin ±15-kV IEC ESD protection domain; 1 µF bypass capacitor between VCC and GND required for IEC ESD compliance.
16 VCC power_in Supply voltage; recommended operating range 3 V to 5.5 V; typical ICC = 300 µA, maximum ICC = 1 mA with no load.
