SP3223EBEY-L

MaxLinear · Pre-ordered Chips · TSSOP-20

SP3223EBEY-L from MaxLinear, in a TSSOP-20. 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 into high-Z state.
2 C1+ passive Positive terminal of the voltage doubler charge-pump capacitor.
3 V+ power_out Regulated +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 Regulated -5.5V output generated by the charge pump.
8 T2OUT output RS-232 driver output 2, with outputs protected against infinite short-circuits to ground.
9 R2IN input RS-232 receiver 2 input, with a typical 5kΩ internal pull-down to ground that holds the output HIGH when left unconnected.
10 R2OUT output TTL/CMOS receiver 2 output.
11 STATUS output TTL/CMOS output indicating the online and shutdown status, going LOW when the device is shut down.
12 T2IN input TTL/CMOS driver 2 input.
13 T1IN input TTL/CMOS driver 1 input.
14 ONLINE input Apply logic HIGH to override AUTO ON-LINE circuitry and keep drivers active, with SHUTDOWN also at logic HIGH.
15 R1OUT output TTL/CMOS receiver 1 output.
16 R1IN input RS-232 receiver 1 input.
17 T1OUT output RS-232 driver output 1, with outputs protected against infinite short-circuits to ground.
18 GND power_in Ground reference.
19 VCC power_in Supply voltage input, +3.0V to +5.5V.
20 SHUTDOWN input Apply logic LOW to shut down the drivers and charge pump, overriding all AUTO ON-LINE circuitry and ONLINE.
