CD4052B: Does the CD4052 have diode clamp current function?

Part Number: CD4052B
Other Parts Discussed in Thread: TMUX4052

Hi Team

My customer is testing the CD4052. They want to know if the CD4052 has "diode clamp current" function. The customer knows that our new part TMUX4052PWR has clear description of this feature in the datasheet, as shown in the screenshot below. They hope to confirm with TI whether the CD4052 has similar function. Please see the following screenshot for the description of this feature in TMUX4052PWR. 

 

 

Below is from TMUX4052PWR datasheet, but CD4052 datasheet didn't have such information.

Thanks.

    Hi GW,

    Yes, you are correct the CD4052 does not show this information, but typically for a older device design it would likely be +/- 10mA. Because the TMUX4052 is a new p2p device the internal diodes may have a higher tolerance at +/-30mA.

    Thank you,

    Arya
