Part Number: CD4051B

Hello Apps support team,

Could you give me comments on the following the customer questions?

<Customer question>

1. Could you tell me the minimum on resistance at -55C, 25C, 125C, respectively?

2. Could you tell me the minimum and maximum output cap (Cos) ?

 Thank you for your support.

 

Best regards,

    Takeshi-san,

    1) TI doesn't provide minimum specifications for Ron parameters because most customers desire lower on-state resistance devices. The minimum specification would also require production testing and scrapping of material that is potentially better performing Ron material would not make it to the customer.

    What is connected to the switch that requires the minimum value for on-state resistance? Most customers use the max value in their designs to know the worst case scenarios.

    Is there a competitive device that specifies a minimum on-state resistance?

    2) On-state capacitance will not vary much across temperature ~ +/-10%

    Thank you,
    Adam
