SN74HC4851-Q1: Crosstalk parameter

RYO

Part Number: SN74HC4851-Q1
Other Parts Discussed in Thread: TMUX1308-Q1

Hi all,

SN74HC4851-Q1 datasheet mentions "Low Crosstalk Between Switches." Can you tell me how low the crosstalk between switches if you have any information?

Regards,
RYO

    Hi RYO,

    There seems to be a mistake in the datasheet - we don't have any information on the crosstalk for this switch. It is an older part so it may have been lost over time.

    That being said we do have an upgraded, and cheaper, version of this part - the TMUX1308-Q1 which does have its crosstalk rated at -110dB for 100KHz and -90dB for 1MHz. 

    Also - what is drawing you towards the SN74HC4851-Q1 in particular? 

    Please let me know!

    Best,

    Hi Parker,

    Thank you for your reply. I'm just comparing TMUX1308-Q1 and this device. The almost all datasheet parameters look similar and TMUX1308-Q1 is cheaper, so I will recommend TMUX1308-Q1 to the customer if there are no concerns about the small differences such as absolute max supply voltage and etc.

    Regards,
