Per the datasheet, the HV5530 data hold-time requirement is 10nsec but that is only guaranteed when the part is operated at-spec. Cant really say if the timing requirements are met with 5V signal-levels even with the measured hold-time of 30nsec. Clock pulsewidth is spec'd at 62nsec, but again,

Hello Steve, Thanks for that. I'm not sure what to make of it. Since Monday, I've sent out 65 replies to various incoming emails, with no problems or issues. I'm NOT very computer savvy to be honest with you, especially the internal workings of the internet. I'm not even sure what an I.P. a

I find it easier to use a couple mosfets to do the level shifting for the HV-. They are inexpensive and take barely any space in the board. Although the solution presented by Phillips in the link below is bi-directional, it is my go-to solution for uni-directional level shifting as well. h
