ADG1201 https://www.analog.com/media/en/technical-documentation/data-sheets/ADG1201.pdf ..Page 5 seems to say this, but it runs with digital inputs down to 2V, so i wondered if 5V is a little higher than the real minimum Vdd?

What do you mean by digital input down to 2V? I see 2V is specified as Vinh. Is this what you mean? --> 2V is the standard TTL Vih_min level Klaus Last edited: Jan 2, 2022 Upvote 0 Downvote

That's the minimum digital logic-level threshold voltage with a 5V supply. The 74HC4016 quad switch will operate down to a 2V supply. Upvote 0 Downvote

So you are able to control the switch with a MCU supplied by e.g. 3.3 V while the switch itself is powered by 5 V or even 15 V. BR Upvote 0 Downvote
