TPS549A20: TPS549A20 SDA/SCL pin capacitance

Part Number: TPS549A20
Other Parts Discussed in Thread: TPS40400

I have a customer inquiry regarding the SDA/SCL pin capacitance on the TPS549A20. Do you happen to know this value or be able to provide a rough estimate? It is not specified in the datasheet.

John,

I doubt that we would have that info, but I will check. I'll let you know what I find out.

John,

We specified this when we released the TPS40400 with a typical value of 0.7pF. The TPS549A20, which is on a similar design process, should be similar, about 1pF and well below the 10pF recommended maximum under the SMBUS spec.

Thanks John. I think this should be adequate for the customer's purposes.
