SP3232EBEA-L

MaxLinear · RS232 ICs · SSOP-16

SP3232EBEA-L from MaxLinear, in a SSOP-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; connect 0.1µF minimum capacitor.
2 V+ power_out Charge pump output generating +5.5V from single 3.0V to 5.5V supply for RS-232 driver operation.
3 C1- passive Negative terminal of the voltage doubler charge-pump capacitor; connect 0.1µF minimum capacitor.
4 C2+ passive Positive terminal of the inverting charge-pump capacitor; connect 0.1µF minimum capacitor.
5 C2- passive Negative terminal of the inverting charge-pump capacitor; connect 0.1µF minimum capacitor.
6 V- power_out Charge pump output generating -5.5V from single 3.0V to 5.5V supply for RS-232 driver operation.
7 T2OUT output RS-232 transmitter 2 driver output with inverting logic; delivers ±5.0V minimum to ±5.4V typical voltage swing with 3kΩ load.
8 R2IN input RS-232 receiver 2 input accepting signal voltages from -15V to +15V with 300mV typical hysteresis margin.
9 R2OUT output TTL/CMOS receiver 2 output with inverting logic; output voltage 0.4V typical at 1.6mA sink or VCC-0.1V at 1.0mA source.
10 T2IN input TTL/CMOS transmitter 2 driver input; logic threshold LOW 0.8V, HIGH 2.0V at VCC=3.3V.
11 T1IN input TTL/CMOS transmitter 1 driver input; logic threshold LOW 0.8V, HIGH 2.0V at VCC=3.3V.
12 R1OUT output TTL/CMOS receiver 1 output with inverting logic; output voltage 0.4V typical at 1.6mA sink or VCC-0.1V at 1.0mA source.
13 R1IN input RS-232 receiver 1 input accepting signal voltages from -15V to +15V with 300mV typical hysteresis margin.
14 T1OUT output RS-232 transmitter 1 driver output with inverting logic; delivers ±5.0V minimum to ±5.4V typical voltage swing with 3kΩ load.
15 GND power_in Ground connection; reference potential for all signal and supply pins.
16 VCC power_in Supply voltage input; accept 3.0V to 5.5V for true RS-232 operation with on-board charge pump.
