'Help with PicStart hardware'

I'm trying to find the manufacturer of a IC in the
PicStart board, it's a SO8 dual SPST switch and it's
marked H721A.
I've found the analog device ADG721, but I'd like to know
others manufacturers.

Friendly Regards

I think its a diode network to clip any voltages over VDD or
VPP. Have a closer look.

No, it's not, I'm sure it's a SPST switch.
