MAX232IDR from Texas Instruments, in a SOIC-16. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | C1+ | passive | Positive lead of C1 capacitor; 1µF external capacitor required for charge pump circuit |
| 2 | VS+ | power_out | Positive charge pump output for storage capacitor only; approximately +10V at 5V supply input |
| 3 | C1- | passive | Negative lead of C1 capacitor; 1µF external capacitor required for charge pump circuit |
| 4 | C2+ | passive | Positive lead of C2 capacitor; 1µF external capacitor required for charge pump circuit |
| 5 | C2- | passive | Negative lead of C2 capacitor; 1µF external capacitor required for charge pump circuit |
| 6 | VS- | power_out | Negative charge pump output for storage capacitor only; approximately -10V at 5V supply input |
| 7 | T2OUT | output | RS232 line data output (to remote RS232 system); outputs ±5V to ±7V with 3kΩ load resistance |
| 8 | R2IN | input | RS232 line data input (from remote RS232 system); accepts ±30V input levels with 1.3V typical threshold |
| 9 | R2OUT | output | Logic data output (to UART); outputs from 0V to VCC logic levels |
| 10 | T2IN | input | Logic data input (from UART); accepts TTL/CMOS input levels 0.8V to 2V |
| 11 | T1IN | input | Logic data input (from UART); accepts TTL/CMOS input levels 0.8V to 2V |
| 12 | R1OUT | output | Logic data output (to UART); outputs from 0V to VCC logic levels |
| 13 | R1IN | input | RS232 line data input (from remote RS232 system); accepts ±30V input levels with 1.3V typical threshold |
| 14 | T1OUT | output | RS232 line data output (to remote RS232 system); outputs ±5V to ±7V with 3kΩ load resistance |
| 15 | GND | power_in | Ground; 0V reference for all logic and supply circuits |
| 16 | VCC | power_in | Supply voltage input; connect to external 4.5V to 5.5V power supply with 5V nominal recommended |
