Analog switch minimum Vdd = 5V?

[cupoftea]

Hi,
Please could i confirm that the minimum single supply Vdd that this Analong switch can run at is 5V?

ADG1201

..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?

Hi,

As you already wrote: page 5 says single supply minimum voltage is 5V.

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

That's the minimum digital logic-level threshold voltage with a 5V supply.

The 74HC4016 quad switch will operate down to a 2V supply.

Hi,

it runs with digital inputs down to 2V

this comes with the 3 V logic-compatible inputs, which are not a function of the used supply voltage. 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.
