MAX3223EEAP+ from Maxim Integrated, in a SSOP-20-208mil. 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 | EN | input | Receiver enable control: drive low for normal operation and high to force the receiver outputs into a high-impedance state. |
| 2 | C1+ | passive | Positive terminal of the voltage doubler charge-pump capacitor, with 0.1µF required for 3.3V operation. |
| 3 | V+ | power_out | +5.5V supply generated by the charge pump. |
| 4 | C1- | passive | Negative terminal of the voltage doubler charge-pump capacitor. |
| 5 | C2+ | passive | Positive terminal of the inverting charge-pump capacitor. |
| 6 | C2- | passive | Negative terminal of the inverting charge-pump capacitor. |
| 7 | V- | power_out | -5.5V supply generated by the charge pump. |
| 8 | T2OUT | output | RS-232 transmitter output, guaranteed at least ±5.0V under loaded conditions and forced to high impedance when disabled. |
| 9 | R2IN | input | RS-232 receiver input with an input voltage range of ±25V. |
| 10 | R2OUT | output | TTL/CMOS inverting three-state receiver output. |
| 11 | INVALID | output | Output of the valid signal detector, enabled high when a valid RS-232 level is present on any receiver input. |
| 12 | T2IN | input | TTL/CMOS transmitter input, which has no pull-up resistor. |
| 13 | T1IN | input | TTL/CMOS transmitter input, which has no pull-up resistor. |
| 14 | FORCEON | input | Drive high to override the automatic circuitry and keep transmitters and charge pump on, provided FORCEOFF is high. |
| 15 | R1OUT | output | TTL/CMOS inverting three-state receiver output. |
| 16 | R1IN | input | RS-232 receiver input with an input voltage range of ±25V. |
| 17 | T1OUT | output | RS-232 transmitter output, guaranteed at least ±5.0V under loaded conditions and forced to high impedance when disabled. |
| 18 | GND | power_in | Ground reference for the device. |
| 19 | VCC | power_in | Supply voltage of +3.0V to +5.5V. |
| 20 | FORCEOFF | input | Force-off input, active low: drive low to shut down the transmitters and on-board charge pump, overriding AutoShutdown and FORCEON. |
