Part Number: SN74LV4051A

Hi team,

My customer wants to know what is the A,B,C pins current requirements and pull-up resistor's resistance limitation for SN74LV4051ADR?

Thanks!

Best Regards,

Bowen

    Hello Bowen,

    The current limitations for the devices input pins can be found in Section 6.1 on the datasheet. For more information please look at this FAQ

    In addition,

    The value of the pullup resistor depends on the operating frequency, the load capacitance, and the desired rise time of the signal. Generally something like a 3.3Kohm pull up resistor is sufficient for most applications.

    Check out this FAQ for more information.
