MAX3232ESE-HXY from HXY MOSFET, in a SOP-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 | Terminal for the positive charge-pump C1 capacitor (one of four 1.0µF external capacitors). |
| 2 | V+ | power_out | Positive voltage generated by the charge pump; the datasheet gives the transmitter high output as VCC-0.3 V minimum, and V+ must not exceed the absolute maximum of VCC+... (V+ is an internally generated rail, not a supply input). |
| 3 | C1- | passive | Terminal for the negative charge-pump C1 capacitor (one of four 1.0µF external capacitors). |
| 4 | C2+ | passive | Terminal for the positive charge-pump C2 capacitor (one of four 1.0µF external capacitors). |
| 5 | C2- | passive | Terminal for the negative charge-pump C2 capacitor (one of four 1.0µF external capacitors). |
| 6 | V- | power_out | Negative voltage generated by the charge pump; the absolute maximum rating for transmitter low output voltage is -7.0 V minimum. |
| 7 | T2OUT | output | RS-232 driver output at RS-232 levels; transmitter output short-circuit current is rated ±60 mA. |
| 8 | R2IN | input | RS-232 receiver input at RS-232 levels; receiver input voltage is rated -12 V to 12 V. |
| 9 | R2OUT | output | RS-232 receiver output at TTL/CMOS levels. |
| 10 | T2IN | input | RS-232 driver input at TTL/CMOS levels; transmitter input voltage range is 0 V to VCC. |
| 11 | T1IN | input | RS-232 driver input at TTL/CMOS levels; transmitter input voltage range is 0 V to VCC. |
| 12 | R1OUT | output | RS-232 receiver output at TTL/CMOS levels. |
| 13 | R1IN | input | RS-232 receiver input at RS-232 levels; receiver input voltage is rated -12 V to 12 V. |
| 14 | T1OUT | output | RS-232 driver output at RS-232 levels; transmitter output short-circuit current is rated ±60 mA. |
| 15 | GND | power_in | Ground reference for the device. |
| 16 | VCC | power_in | Supply voltage input; the datasheet gives a supply range of 3 V to 5.5 V. |
