There seem to be so many nearly identical products from Microchip. I have been experimenting the HV5622 which has 32 outputs,etc.etc.etc - it is also available in SMD format if desired. Yes, it needs (likes) 12V levels though on the bench right now I have one clocking away being driven entirely by a WeMos at 3V3 levels - totally out of spec I know. I plan to be shifting levels to 12V using 2N7000's for the 'real' thing - but they have not turned up yet!
It might help you to know (you may already know) that Microchip offer a 'samples' service so you could get some for 'evaluation' purposes.
