Other Parts Discussed in Thread: SN74LVCH16T245-EP

Hi,

What is the maximum acceptable Junction Temperature, Junction-to-Case Thermal Resistance (theta - JC)  and
Junction-to-Ambient Thermal Resistance (theta - JA) for the following devices
1) 74AVCH1T45DCKTG4
2) SN74LVCH16T245-EP
3) SN74LVCH16240ADGGR

  • Hello Goutham,

    1) The absolute maximum junction temperature for the 74AVCH1T45DCKTG4 is 150°C. For the other specifications on this part please refer below.

    2) For the SN74LVCH16T245-EP part the responsibility belongs to the High Reliability forum. Please post your question regarding this part in this forum : 

    3)For the SN74LVCH16240ADGGR part I have notified the appropriate engineers and they will respond shortly.

  • hello Shreyas ,

    Thanks for the response.

    What is the maximum acceptable junction temperature for the devices  SN74LVCH16240ADGGR and SN74LVCH16T245-EP ?

  • Goutham ,

    The max junction temp will be usually mentioned in the abs max ratings table to be 150C for most of the logic devices.
