SN74LVC16373A: SN74LVC16373A <Maximum Power Dissipation>

Part Number: SN74LVC16373A
Other Parts Discussed in Thread: SN74LVC16373

Hi, Team.

could you tell me about it as subject shown?

As SN74LVC16373 has such an information but not for SN74LVC16373A.

could you give us?

  • Hi,

    That is no issue, the value can be quickly calculated using the following equation found in this FAQ: https://e2e.ti.com/support/logic/f/151/t/716179?tisearch=e2e-quicksearch&keymatch=FAQ%20max%20power

    Pmax(W) = (TJ(max)(°C) - TA(max)(°C)) / θJA(°C/W)

    Pmax := maximum power consumption before thermal failure

    TJ(max) := maximum junction temperature (150°C for standard logic devices, unless otherwise stated in the datasheet)

    TA(max) := maximum ambient temperature of operation

    θJA := junction-to-ambient thermal resistance (found in datasheet)

    So as in the datasheet example, with a 55C TA and 68.4 θJA for the DL package:

    Pmax = (150-55)/(68.4) = 1.388W

    This is the power you can apply to the device before it fails. It is usually very unlikely that you will be able to apply that much power to the part before getting another issue.

    Thanks!
