SP3220EEY-L

MaxLinear · RS232 ICs · TSSOP-16

SP3220EEY-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 and logic HIGH to disable the receiver outputs (high-Z state).
2 C1+ passive Positive terminal of the voltage doubler charge-pump capacitor (C1 must be 0.1µF for 3.3V operation and 0.22µF for 3.0V to 5.5V operation).
3 V+ power_out +5.5V output generated by the charge pump, regulated to +5.5V regardless of VCC over the +3.0V to +5.5V range.
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, regulated to a minimum of -5.5V.
8 R1IN input RS-232 receiver input, with an internal 5kΩ pull-down that commits R1OUT to HIGH if left unconnected; input range is ±15V.
9 R1OUT output TTL/CMOS receiver output (inverting, high-impedance when EN is HIGH; not affected by SHDN).
10 N.C. unconnected No connect; not internally connected.
11 T1IN input TTL/CMOS driver input; the driver has no pull-up, so unused inputs should be tied to VCC or GND.
12 N.C. unconnected No connect; not internally connected.
13 T1OUT output RS-232 driver output, tri-stated in shutdown and protected against infinite short-circuits to ground.
14 GND power_in Ground reference for the device.
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 drivers (high-Z output) and the on-board power supply (supply current falls to less than 1µA).
