MAX3232MPWREP

Texas Instruments · RS232 ICs · TSSOP-16

MAX3232MPWREP 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 terminal of charge-pump capacitor C1 (0.1 µF at VCC = 3.3 V ±0.3 V, 0.047 µF at 5 V ±0.5 V).
2 V+ power_out Positive charge-pump output supply, abs max -0.3 to 7 V, with a capacitor C3 connected to VCC or GND.
3 C1− passive Negative terminal of charge-pump capacitor C1.
4 C2+ passive Positive terminal of charge-pump capacitor C2 (0.1 µF at VCC = 3.3 V ±0.3 V, 0.33 µF at 5 V ±0.5 V).
5 C2− passive Negative terminal of charge-pump capacitor C2.
6 V− power_out Negative charge-pump output supply, abs max 0.3 to -7 V, with capacitor C4 to ground.
7 DOUT2 output RS-232 driver 2 output with ±15 kV HBM ESD protection, swings at least ±5 V into 3 kΩ.
8 RIN2 input RS-232 receiver 2 input with ±15 kV HBM ESD protection, input range ±25 V and 5 kΩ nominal input resistance.
9 ROUT2 output Logic-level receiver 2 output, high level at least VCC-0.6 V at -1 mA and low level at most 0.4 V at 1.6 mA.
10 DIN2 input Driver 2 logic input, 0 to 5.5 V, VIL max 0.8 V, VIH min 2 V at 3.3 V supply or 2.4 V at 5 V supply.
11 DIN1 input Driver 1 logic input, 0 to 5.5 V, VIL max 0.8 V, VIH min 2 V at 3.3 V supply or 2.4 V at 5 V supply.
12 ROUT1 output Logic-level receiver 1 output, high level at least VCC-0.6 V at -1 mA and low level at most 0.4 V at 1.6 mA.
13 RIN1 input RS-232 receiver 1 input with ±15 kV HBM ESD protection, input range ±25 V and 5 kΩ nominal input resistance.
14 DOUT1 output RS-232 driver 1 output with ±15 kV HBM ESD protection, swings at least ±5 V into 3 kΩ.
15 GND power_in Ground, reference for all voltages and protected by ±15 kV ESD pin to pin.
16 VCC power_in Supply voltage, 3 V to 5.5 V (3 to 3.6 V or 4.5 to 5.5 V), abs max -0.3 to 6 V, with 0.1 µF bypass capacitor.
