MAX3232IDR from TECH PUBLIC, in a SOP-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 lead of C1 charge-pump capacitor; connect 0.1 µF (3.3 V/3-5.5 V) or 0.047 µF (5 V) ceramic capacitor between C1+ and C1-.
2 V+ power_out Positive charge-pump output (~+5.5 V internal rail); connect storage capacitor (0.1-0.47 µF) from V+ to GND; for internal use only.
3 C1- passive Negative lead of C1 charge-pump capacitor; connect external capacitor between C1+ and C1-.
4 C2+ passive Positive lead of C2 charge-pump capacitor; connect 0.1-0.47 µF capacitor between C2+ and C2-.
5 C2- passive Negative lead of C2 charge-pump capacitor; connect external capacitor between C2+ and C2-.
6 V- power_out Negative charge-pump output (~-5.5 V internal rail); connect storage capacitor (0.1-0.47 µF) from V- to GND; for internal use only.
7 DOUT2 output RS-232 Driver Output channel 2; driven from DIN2 (TTL/CMOS input); output voltage ±5 V min into 3 kΩ load, short-circuit current ±30-±60 mA max.
8 RIN2 input RS-232 Receiver Input channel 2; accepts ±25 V max; positive-going threshold 1.5-2.4 V (VCC=3.3 V) / 2.0-2.4 V (VCC=5 V).
9 ROUT2 output TTL/CMOS Receiver Output channel 2; inverted logic output of RIN2; V_OH ≥ VCC-0.3 V, V_OL ≤ 0.4 V at I_O=1.6 mA.
10 DIN2 input TTL/CMOS Driver Input channel 2; high-level V_IH ≥ 2 V (VCC≥3.3 V) / 2.4 V (VCC=5 V); low-level V_IL ≤ 0.8 V; drives DOUT2.
11 DIN1 input TTL/CMOS Driver Input channel 1; high-level V_IH ≥ 2 V (VCC≥3.3 V) / 2.4 V (VCC=5 V); low-level V_IL ≤ 0.8 V; drives DOUT1.
12 ROUT1 output TTL/CMOS Receiver Output channel 1; inverted logic output of RIN1; V_OH ≥ VCC-0.3 V, V_OL ≤ 0.4 V at I_O=1.6 mA.
13 RIN1 input RS-232 Receiver Input channel 1; accepts ±25 V max; positive-going threshold 1.5-2.4 V (VCC=3.3 V) / 2.0-2.4 V (VCC=5 V).
14 DOUT1 output RS-232 Driver Output channel 1; driven from DIN1 (TTL/CMOS input); output voltage ±5 V min into 3 kΩ load, short-circuit current ±30-±60 mA max.
15 GND power_in Ground reference; 0 V supply return for VCC and all internal circuitry.
16 VCC power_in Positive supply voltage; operating range 3 V to 5.5 V; supply current 1.5 mA typ at no load (3.3 V or 5 V).
