MaxLinear · RS232 ICs · SOIC-16

SP3232EBCN-L from MaxLinear, 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 terminal of the voltage doubler charge-pump capacitor; requires 0.1µF external capacitor to C1-.
2 V+ power_out +5.5V internal supply rail generated by the charge pump; absolute maximum magnitude 7V.
3 C1- passive Negative terminal of the voltage doubler charge-pump capacitor; requires 0.1µF external capacitor to C1+.
4 C2+ passive Positive terminal of the inverting charge-pump capacitor; requires 0.1µF external capacitor to C2-.
5 C2- passive Negative terminal of the inverting charge-pump capacitor; requires 0.1µF external capacitor to C2+.
6 V- power_out −5.5V internal supply rail generated by the charge pump; absolute maximum magnitude −7V.
7 T2OUT output RS-232 driver output; ±5.0V minimum swing into 3kΩ load, slew rate ≤30V/µs, ±15kV HBM ESD, short-circuit protected.
8 R2IN input RS-232 receiver input; input voltage range −15V to +15V, input resistance 3-7kΩ, 300mV hysteresis, ±15kV HBM ESD.
9 R2OUT output TTL/CMOS receiver output; VOL ≤0.4V at IOUT=1.6mA, VOH ≥VCC−0.6V at IOUT=−1.0mA.
10 T2IN input TTL/CMOS driver input; VIL ≤0.8V, VIH ≥2.0V (VCC=3.3V), input leakage ±1.0µA max.
11 T1IN input TTL/CMOS driver input; VIL ≤0.8V, VIH ≥2.0V (VCC=3.3V), input leakage ±1.0µA max.
12 R1OUT output TTL/CMOS receiver output; VOL ≤0.4V at IOUT=1.6mA, VOH ≥VCC−0.6V at IOUT=−1.0mA.
13 R1IN input RS-232 receiver input; input voltage range −15V to +15V, input resistance 3-7kΩ, 300mV hysteresis, ±15kV HBM ESD.
14 T1OUT output RS-232 driver output; ±5.0V minimum swing into 3kΩ load, slew rate ≤30V/µs, ±15kV HBM ESD, short-circuit protected.
15 GND power_in Ground reference for all internal circuitry.
16 VCC power_in 3.0V to 5.5V supply voltage; absolute maximum 6.0V; quiescent current 0.3-1.0mA typical at VCC=3.3V.
