Hi Shin,

Apologies for delay.

DDC118 is the last in TI series that supports -40C to +85C. Is this temperature range a must for the customer? If yes, why?

The following are the parts in the TI series (earliest to latest):

DDC11x (up to 8 channels)

DDC316, DDC232, DDC264 (up to 64 channels)

DDC1128 (up to 128 channels)

DDC2256 (256 channels)

DDC3256 (256 channels)

Thanks,

Karthik N

Hi Karthik,

Thank you for your reply.

The end customer's requirement is to use industrial products.

Hi Shin,

Understood. Then, DDC118 will be the last product in the DDC series that can support this requirement.

Thanks,
