 SN74AHCT32 | Same pinout as above can be used. This is just an OR gate, but any AHCT gate can be used if inputs are connected appropriately. ;)
 SN74HCT125N | Slower, cheaper version. Works just as well for WS2812, but not recommended for APA102.

-TXS0102, TXS0108 | Bidirectional levelshifters that may work fine with WLED (if possible, 74AHCT gates should be preferred as they support both longer data lines and faster protocols)
+TXS0102, TXS0108 | Not recommended: these bidirectional levelshifters do work but only for short data lines (less than 50cm).
