What are these schematic symbols in the HCPL3700? (square with arrows and overlapped circle)

Question

I am working with HCPL3700 to sense mains.

In the datasheet it has these symbols:

What are those symbols? What are their functions?

The overlapping circles are a current source. Partial duplicate: https://electronics.stackexchange.com/q/56670/2028 — JYelton, Oct 20 '21 at 22:01
they are actually block diagram symbols ... they each represent multiple components — jsotola, Oct 20 '21 at 23:52
Thanks @jsotola! I was missing that and looking for one component for each :S — Carlos Garcia, Oct 21 '21 at 08:15

The square with arrows is hysteresis, as evidenced by some of the electrical characteristics of the device.

The overlapping circles are a current source.
