HGX3232ECMT 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 | Positive terminal for the first charge pump capacitor, which uses a 0.1 µF capacitor for 3.3V operation. |
| 2 | V+ | power_out | Doubled voltage terminal generated by the charge pump; V+ may have a maximum magnitude of +7V and 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; V- may have a maximum magnitude of 7V and its absolute addition with V+ must not exceed 13 V. |
| 7 | T2OUT | output | Second RS-232 transmitter output, with a transmitter output voltage range of ±13.2 V. |
| 8 | R2IN | input | Second RS-232 receiver input, with a receiver input voltage operating range of -25 V to 25 V. |
| 9 | R2OUT | output | Second receiver TTL/CMOS output, referenced to VCC. |
| 10 | T2IN | input | Second transmitter logic input, with a transmitter input voltage range of -0.3 V to 6 V. |
| 11 | T1IN | input | First transmitter logic input, with a transmitter input voltage range of -0.3 V to 6 V. |
| 12 | R1OUT | output | First receiver TTL/CMOS output, referenced to VCC. |
| 13 | R1IN | input | First RS-232 receiver input, with a receiver input voltage operating range of -25 V to 25 V. |
| 14 | T1OUT | output | First RS-232 transmitter output, with a transmitter output voltage range of ±13.2 V. |
| 15 | GND | power_in | Ground reference for the device. |
| 16 | VCC | power_in | Supply voltage, 3.3 V to 5.5 V. |
