TS12A44514: V,IH at VCC = 12V

Part Number: TS12A44514
Other Parts Discussed in Thread: MUX509

Team-

For VCC = 12V, page 6 of data sheet indicates that VIH,min = 5V. 

However, section 8.1.1, page 11, states that "...When Vcc reaches 12V, the level threshold is about 3V".

I need to drive this device with 3.3V logic, while VCC = 12V. 

Please confirm that this will work, and please clarify the data sheet either by updating the parametric data or removing this language from 8.1.1.

Thanks, Best, Steve

    Steve,

    Please use the value stated in the electrical specification table Vih min = 5V when Vcc = 12 V.

    I agree the that page 11 has poorly worded statement letting customers know that the Vih min level is proportional to Vcc.  I will submit this to our datasheet error and change backlog. 

    If you would like a device that can pass 12 V signals with logic control at 3.3 V signals look at our MUX family of switches like MUX509

    Sorry for the confusion.  Let me know if you have additional questions.

    Thank you,

    Adam

    Thanks, please consider removing the other language in the data sheet that I pointed out.

    It's misleading and confusing.

    Thanks again, best, Steve
