TLC2558: replace TLC2558 to TLV2548 II

Kazuhiko Hirano

Part Number: TLC2558
Other Parts Discussed in Thread: TLV2548

Hello,

My customer considers to replace TLC2558 with TLV2548 at their current production because of delivery issue, and looking into the delta between them.

TLC2558 datasheet specified the following five recommended operating conditions surrounded by red, but they are not specified in the TLV2548 datasheet.

What are those five conditions at TLV2548?

Best regards,

Hi Hirano-san,

You need to compare the timing diagrams. There is no direct equivalent for tt(CLK) in the TLV2548 datasheet. For the second line, the parameter would be the same as t(CSL-FSH). th(SCLK-CS) is the same as td(SCLK-CSH). The last two parameters have the same diagram names.

Tom,

Thank you for your response.

However, I can not find the last one, td(EOCH-DOZ) in the TLV2548 datasheet.

How much it is at TLV2548?

Best regards,

Hi Hirano,

I see that the td(EOCH-DOZ) is not listed in the table, it should be the same values as the TLC2558.
