Part Number: HD3SS3412

Hi,

Datasheet specifies 4.7mA typical supply current for HD3SS3412, while TI.com  parameter search gives 3.6uA. Is there a mistake in datasheet? 4.7mA feels quite high for a passive switch.

Thanks!

Rgds,

  • based on power data, 4.7ma should be right. where did you find 3.6ua data, maybe is idle current.

    Can you explain that a bit further? According to DS max power dissipation is 4.4mW. When power dissipation is calculated with 3.6V supply voltage and max Idd, we have 3.6V*6mA=21.6mW meaning it is not matching.

    HD3SS3412 is passive switch so is not driving termination resistors. Where is all that current going?

    ok, let me check and make sure which is right.

    Any updates yet?

    typical ICC should be 1.2ma, we need to update datasheet.
