SP3220ECY-L

MaxLinear · RS232 ICs · TSSOP-16

SP3220ECY-L from MaxLinear, 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 EN input Receiver enable: apply logic LOW for normal operation; logic HIGH disables the receiver outputs to high-impedance.
2 C1+ passive Positive terminal of the voltage doubler charge-pump capacitor.
3 V+ power_out +5.5V output generated by the charge pump.
4 C1- passive Negative terminal of the voltage doubler charge-pump capacitor.
5 C2+ passive Positive terminal of the inverting charge-pump capacitor.
6 C2- passive Negative terminal of the inverting charge-pump capacitor.
7 V- power_out -5.5V output generated by the charge pump.
8 R1IN input RS-232 receiver input.
9 R1OUT output TTL/CMOS receiver output.
10 N.C. unconnected No connect.
11 T1IN input TTL/CMOS driver input; the driver inputs have no internal pull-up, so unused inputs should be tied to VCC or GND.
12 N.C. unconnected No connect.
13 T1OUT output RS-232 driver output; it is tri-stated in shutdown (SHDN LOW).
14 GND power_in Ground.
15 VCC power_in +3.0V to +5.5V supply voltage.
16 SHDN input Shutdown control input: drive HIGH for normal device operation; drive LOW to shut down the drivers (high-Z output) and the onboard power supply.
