Hi,
Please help me in choosing the type if IC. My input is 28V DC, if i give an enable signal as 3.3V, then my IC should pass the input voltage i.e 28V as output. I know it can be done using FET. But i have to implement it with IC, I dono what type of IC to choose. Please give me some suggestions.
IF the supply is 5V, SN7407 buffer (or similar) is an option, but 30V max. Vout could be an issue, so close to 28V. If the supply available is only 3.3V, not possible with this (old) IC.
Not that isolation is a requirement, but an optocoupler could be used for this, too.
