SN74LV4051A: SN74LV4051A with latch function...

This device is a passive switch; it does not have inputs or outputs.

It's possible that you want something like the SN74HC259.

Please describe the actual problem you're trying to solve.

Sorry and let me explain it!

Since I can use COM pin as input and Yn pins as output, what I want is, at the 1st time, I choose Y0 on and the output is high, then I choose Y6 on and output is low, but I need Y0 keeps "HIGH" untill I choose and changed it.

If after 2nd time, I choose Y7 on, then output low, what I want to get are: Y0=high, Y6=low, and Y7=low, and so on.

This sounds like a problem that can be solved with an addressable latch.

Hey Peter,

As Clemens mentioned this is a passive switch so the SN74LV4051A won't be able to provide this function. I'm going to loop in the logic team to see if we can find you the right fit.

Thanks Rami!

Hi Peter,

I feel Clemens offered a great device option to achieve the desired functionality. Let me know if the SN74HC259 function is what you are after. 

Dears,

Thanks for the reply.

I will check with the customer.

Thanks.

Hey Peter,

Great, let me know what they think.
