Hello, it´s my first time here, so don´t know how basic my question is.

I´d like to use a CD4026B in a counter application. My big doubt is, when I apply a high level on pin 2, will the current output to the display remain fixed? i.e. I need to freeze the display at the count which existed before the high level on pin 2 (inhibit count).
 

The short answer is yes.
when you inhibit count you effectively stop the clock signal to the flip-flops. Once there is no clock the outputs of flip-flops remain unchanged and so the output of the chip remains unchanged (page 3 of the attached datasheet).

By the logic diagram, this is what I suspected. Thanks to all who answered.
