MAX3232IPWRG4 from Texas Instruments, 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 lead of the C1 charge-pump capacitor; its value is selected by VCC per Table 9-1 (0.1 µF at 3.3 V, 0.047 µF at 5 V). |
| 2 | V+ | power_out | Positive charge-pump output used only for its storage capacitor; the absolute maximum on V+ is -0.3 V to 7 V. |
| 3 | C1- | passive | Negative lead of the C1 charge-pump capacitor. |
| 4 | C2+ | passive | Positive lead of the C2 charge-pump capacitor; C2 to C4 are 0.1 µF at 3.3 V, 0.33 µF at 5 V (Table 9-1). |
| 5 | C2- | passive | Negative lead of the C2 charge-pump capacitor. |
| 6 | V- | power_out | Negative charge-pump output used only for its storage capacitor; the absolute range on V- is -7 V to 0.3 V. |
| 7 | DOUT2 | output | RS-232 line driver output to the remote RS-232 system, specified at VOH of at least 5 V and VOL of at most -5 V with a 3 kΩ load to GND. |
| 8 | RIN2 | input | RS-232 line receiver input from the remote RS-232 system, with an input voltage range of -25 V to 25 V and an internal 3 kΩ to 7 kΩ input resistance. |
| 9 | ROUT2 | output | Logic data output to the UART, with VOH of at least VCC - 0.6 V at IOH = -1 mA. |
| 10 | DIN2 | input | Logic data input from the UART, which must be held at a valid high or low level; VIH is 2 V at 3.3 V VCC or 2.4 V at 5 V VCC and VIL is at most 0.8 V. |
| 11 | DIN1 | input | Logic data input from the UART, which must be held at a valid high or low level; VIH is 2 V at 3.3 V VCC or 2.4 V at 5 V VCC and VIL is at most 0.8 V. |
| 12 | ROUT1 | output | Logic data output to the UART, with VOH of at least VCC - 0.6 V at IOH = -1 mA. |
| 13 | RIN1 | input | RS-232 line receiver input from the remote RS-232 system, with an input voltage range of -25 V to 25 V and an internal 3 kΩ to 7 kΩ input resistance. |
| 14 | DOUT1 | output | RS-232 line driver output to the remote RS-232 system, specified at VOH of at least 5 V and VOL of at most -5 V with a 3 kΩ load to GND. |
| 15 | GND | power_in | Ground reference for all device voltages; all absolute maximum and operating voltages are referenced to GND. |
| 16 | VCC | power_in | Supply voltage input, connected to an external 3 V to 5.5 V supply (absolute maximum -0.3 V to 6 V). |
