CD74HC4052: Please provide the Rds(on) @ Vcc = 3.3 V

Part Number: CD74HC4052


Please provide the Rdson of CD74HC4052 device with Vcc = 3.3 V.  The datasheet only shows Rdson with Vcc = 4.5 V.

Thank you,


  • Hi Adam,

    Can you provide us with a better understanding of why Rdson at VCC = 3.3V is critical in your system? We do not currently have this data on-hand but can look further into this.



  • In reply to Dakotah:


    I set the Vcc of the device to 3.3V and swept the input into the switch from 0V to 3.3V in increments of 0.3V.

    I then connected COM pin to ground and measured the voltage drop across the switch.

    I repeated this for both channels. Please see the plot below for the Ron of the device for both channels A and B.

    Thank you,
