ID of this SOT23-6 level shifter in SP511e LED controller?

[GnatGoSplat]

Tinkering around with my SP511e LED controller flashed to WLED, I seem to have managed to bust a pin off the GPIO level shifter IC which rendered it dead.
I have since bypassed it and it still works without level shifting, but I would just like to know IF I were to repair it, what level shifter is this?

Here is an image showing it (not my SP511e, but you can see people like to hack these):


The level shifter IC appears to be SOT23 6-pin, has "245" marking on top.  Probably not a date code, because they all say "245".
Assuming dot denotes pin 1, pinout is as follows:
1 - output (shorted to 3)
2 - gnd
3 - output (shorted to 1)
4 - input (shorted to 5)
5 - input (shorted to 4)
6 - +5V supply

It converts 3.3V logic to 5V.  It appears to be single-supply, either single input and output or maybe they paralleled a 2-channel IC.  Driving LED strip data bus, so likely unidirectional.  Label on the PCB is "U4".

Any ideas?  AI (both Bing and ChatGPT) are absolutely no help at all.

I wouldn't call it a level shifter. To me it looks more like a dual non-inverting buffer (possibly a Schmitt trigger?). A genuine level shifter would have two supplies.

TI has a couple of devices which might do the job, but their Vcc is on pin #5.

It would probably be a single  gate version of some 74xx245 part - HC, AHCT, LVC, or something like that.  Maybe this one:

The pinout doesn't match.

Yeah, I can't seem to find anything with a matching pinout.  I can't imagine they would have gone to the trouble to make a custom part.
