MAX232EIPWR

Texas Instruments · RS232 ICs · TSSOP-16

MAX232EIPWR from Texas Instruments, in a TSSOP-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 for the charge pump circuit.
2 VS+ power_out Positive charge pump output, nominally +8.5V, for external storage capacitor only.
3 C1- passive Negative lead of C1 capacitor for the charge pump circuit.
4 C2+ passive Positive lead of C2 capacitor for the charge pump circuit.
5 C2- passive Negative lead of C2 capacitor for the charge pump circuit.
6 VS- power_out Negative charge pump output, nominally -8.5V, for external storage capacitor only.
7 DOUT2 output RS-232 line data output for second driver (to remote RS-232 system); output voltage ±5V to ±7V.
8 RIN2 input RS-232 line data input for second receiver (from remote RS-232 system); accepts ±3V to ±30V input.
9 ROUT2 output Logic data output for second receiver (to UART); TTL/CMOS compatible, 0V to VCC.
10 DIN2 input Logic data input for second driver (from UART); TTL/CMOS compatible, accepts 0V to VCC.
11 DIN1 input Logic data input for first driver (from UART); TTL/CMOS compatible, accepts 0V to VCC.
12 ROUT1 output Logic data output for first receiver (to UART); TTL/CMOS compatible, 0V to VCC.
13 RIN1 input RS-232 line data input for first receiver (from remote RS-232 system); accepts ±3V to ±30V input.
14 DOUT1 output RS-232 line data output for first driver (to remote RS-232 system); output voltage ±5V to ±7V.
15 GND power_in Ground; 0V reference for all logic and power signals.
16 VCC power_in Supply voltage; connect to external 5V power supply between 4.5V and 5.5V.
