ST202EBTR from STMicroelectronics, 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	Positive terminal for the first charge pump capacitor; the 0.1 µF (ST202E) or 1 µF (ST232E) capacitor value is given in the typical application table.
2	V+	power_out	Doubled voltage terminal generated by the charge pump; absolute maximum extra positive voltage is (VCC - 0.3) to 14 V.
3	C1-	passive	Negative terminal for the first charge pump capacitor.
4	C2+	passive	Positive terminal for the second charge pump capacitor.
5	C2-	passive	Negative terminal for the second charge pump capacitor.
6	V-	power_out	Inverted voltage terminal generated by the charge pump; absolute maximum extra negative voltage is -14 to 0.3 V.
7	T2OUT	output	Second RS-232 transmitter output; output swing is ±5 V minimum with all transmitter outputs loaded with 3 kΩ to GND, and short-circuit duration is infinite.
8	R2IN	input	Second RS-232 receiver input; operating range is ±30 V with RS-232 input resistance of 3 to 7 kΩ.
9	R2OUT	output	Second receiver TTL/CMOS output; VOL maximum 0.4 V at 3.2 mA and VOH minimum 3.5 V at -1 mA.
10	T2IN	input	Second transmitter TTL/CMOS input; logic threshold low is 0.8 V maximum and threshold high is 2 V minimum.
11	T1IN	input	First transmitter TTL/CMOS input; logic threshold low is 0.8 V maximum and threshold high is 2 V minimum.
12	R1OUT	output	First receiver TTL/CMOS output; VOL maximum 0.4 V at 3.2 mA and VOH minimum 3.5 V at -1 mA.
13	R1IN	input	First RS-232 receiver input; operating range is ±30 V with RS-232 input resistance of 3 to 7 kΩ.
14	T1OUT	output	First RS-232 transmitter output; output swing is ±5 V minimum with all transmitter outputs loaded with 3 kΩ to GND, and short-circuit duration is infinite.
15	GND	power_in	Ground reference for the device.
16	VCC	power_in	Supply voltage; 5 V ±10% operating, absolute maximum -0.3 to 6 V.
