HMAX232EIDR

HXY MOSFET · RS232 ICs · SOP-16

HMAX232EIDR from HXY MOSFET, 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 for the charge-pump C1 capacitor, which sits between C1+ and C1-.
2 V+ power_out Positive voltage generated by the internal charge pump to supply the RS-232 driver high level.
3 C1- passive Negative terminal for the charge-pump C1 capacitor, which sits between C1+ and C1-.
4 C2+ passive Positive terminal for the charge-pump C2 capacitor, which sits between C2+ and C2-.
5 C2- passive Negative terminal for the charge-pump C2 capacitor, which sits between C2+ and C2-.
6 V- power_out Negative voltage generated by the internal charge pump to supply the RS-232 driver low level; the absolute maximum table gives a V- limit of -14 V.
