TDSEMIC · RS232 ICs · SOP-16
MAX3232ESE-TD from TDSEMIC, 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 | Positive terminal of the charge-pump capacitor C1 (1.0µF external). |
| 2 | V+ | power_out | Positive voltage generated by the charge pump, with a 1.0µF capacitor to VCC and an absolute maximum of 9.8V. |
| 3 | C1- | passive | Negative terminal of the charge-pump capacitor C1 (1.0µF external). |
| 4 | C2+ | passive | Positive terminal of the charge-pump capacitor C2 (1.0µF external). |
| 5 | C2- | passive | Negative terminal of the charge-pump capacitor C2 (1.0µF external). |
| 6 | V- | power_out | Negative voltage generated by the charge pump, with a 1.0µF capacitor to ground and an absolute minimum of -9.0V. |
| 7 | T2OUT | output | RS-232 driver 2 output at RS-232 levels. |
| 8 | R2IN | input | RS-232 receiver 2 input at RS-232 levels, with an internal 5K pulldown and an input range of -30V to 30V. |
| 9 | R2OUT | output | RS-232 receiver 2 output at TTL/CMOS levels. |
| 10 | T2IN | input | RS-232 driver 2 input at TTL/CMOS levels. |
| 11 | T1IN | input | RS-232 driver 1 input at TTL/CMOS levels. |
| 12 | R1OUT | output | RS-232 receiver 1 output at TTL/CMOS levels. |
| 13 | R1IN | input | RS-232 receiver 1 input at RS-232 levels, with an internal 5K pulldown and an input range of -30V to 30V. |
| 14 | T1OUT | output | RS-232 driver 1 output at RS-232 levels. |
| 15 | GND | power_in | Ground. |
| 16 | VCC | power_in | Supply voltage input, recommended 3.0V to 5.5V (absolute maximum 6.0V), with a 1.0µF decoupling capacitor. |
