MAX232ECMT from HGSEMI, in a TSSOP-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 Connects to the external charge-pump capacitor of the positive voltage multiplier (datasheet: output of external capacitance of positive voltage multiplier unit); no capacitor value is stated in the text.
2 V+ power_out Positive voltage output of the voltage multiplier, specified at 5.0 V minimum under recommended conditions and limited to VCC-0.3 V to 14 V in absolute maximum ratings.
3 C1- passive Connects to the external charge-pump capacitor of the positive voltage multiplier (datasheet: output of external capacitance of positive voltage multiplier unit); no capacitor value is stated in the text.
4 C2+ passive Connects to the external charge-pump capacitor of the negative voltage multiplier (datasheet: output of external capacitance of negative voltage multiplier unit); no capacitor value is stated in the text.
5 C2- passive Connects to the external charge-pump capacitor of the negative voltage multiplier (datasheet: output of external capacitance of negative voltage multiplier unit); no capacitor value is stated in the text.
6 V- power_out Negative voltage output of the voltage multiplier, specified at -5.0 V minimum under recommended conditions and limited to -14 V to -0.3 V in absolute maximum ratings.
7 T2OUT output RS-232 level transmitter 2 output, delivering at least ±5.0 V into a 3 kΩ load with short-circuit current limited to ±60 mA.
8 R2IN input RS-232 level receiver 2 input, rated for receiver input voltage of -30 V to +30 V.
9 R2OUT output TTL/CMOS level receiver 2 output, with VOH at least 3.5 V (IOH = -1.0 mA) and VOL at most 0.4 V (IOL = 3.2 mA) over the rated temperature range.
10 T2IN input TTL/CMOS level transmitter 2 input, with transmitter input voltage rated from 0 V to VCC.
11 T1IN input TTL/CMOS level transmitter 1 input, with transmitter input voltage rated from 0 V to VCC.
12 R1OUT output TTL/CMOS level receiver 1 output, with VOH at least 3.5 V (IOH = -1.0 mA) and VOL at most 0.4 V (IOL = 3.2 mA) over the rated temperature range.
13 R1IN input RS-232 level receiver 1 input, rated for receiver input voltage of -30 V to +30 V.
14 T1OUT output RS-232 level transmitter 1 output, delivering at least ±5.0 V into a 3 kΩ load with short-circuit current limited to ±60 mA.
15 GND power_in Common ground reference for the device.
16 VCC power_in Supply pin with recommended supply voltage of 4.5 V to 5.5 V and absolute maximum of -0.3 V to 6.0 V (datasheet pin table labels it 'Supply output of voltage source', which conflicts with its use as a supply).
