SP3220EBEY-L

MaxLinear · Pre-ordered Chips · TSSOP-16

SP3220EBEY-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 to disable the receiver output (high-Z).
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, with an internal 5kΩ pull-down to ground.
9 R1OUT output TTL/CMOS receiver output.
10 N.C. unconnected No connect.
11 T1IN input TTL/CMOS driver input, with 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.
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 operation, drive LOW to shut down the driver (high-Z output) and the on-board power supply.
