COSMAX3232ID

COSINE · RS232 ICs · SOP-16

COSMAX3232ID from COSINE, in a SOP-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 the voltage doubler charge-pump capacitor.
2 V+ power_out 5.5 V output generated by the charge pump, with absolute maximum rating of -0.3 V to 8 V.
3 C1- passive Negative terminal of the voltage doubler charge-pump capacitor.
4 C2+ passive Positive terminal of the inverting charge-pump capacitor.
5 C2- passive Negative terminal of the inverting charge-pump capacitor.
6 V- power_out -5.5 V output generated by the charge pump, with absolute maximum rating of -8 V to +0.3 V.
7 TOUT2 output RS-232 driver output, protected against shorts to ground and meeting EIA/TIA-232 levels.
8 RIN2 input RS-232 line input to the receiver, with an input voltage range of -15 V to +15 V.
9 ROUT2 output TTL/CMOS receiver output, with absolute range of -0.3 V to VCC + 0.3 V.
10 TIN2 input TTL/CMOS driver input that must be held at a valid high or low level; unused inputs should be tied to VCC or GND since there is no internal pullup.
11 TIN1 input TTL/CMOS driver input that must be held at a valid high or low level; unused inputs should be tied to VCC or GND since there is no internal pullup.
12 ROUT1 output TTL/CMOS receiver output, with absolute range of -0.3 V to VCC + 0.3 V.
13 RIN1 input RS-232 line input to the receiver, with an input voltage range of -15 V to +15 V.
14 TOUT1 output RS-232 driver output, protected against shorts to ground and meeting EIA/TIA-232 levels.
15 GND power_in Ground reference for the device.
16 VCC power_in Supply voltage, 3.0 V to 5.5 V.
