SN74LVC1G08: SN74LVC1G08QDBVRQ1

Part Number: SN74LVC1G08

Dear TI Team,

As we are supporting BHEL for various projects.

we need power dissipation value for thermal analysis for below parts which is not mentioned in datasheet.

1. SN74LVC1G08QDBVRQ1

2. SN74LVC1G74DCTR

3. SN74LVC1G32QDBVRQ1

4. SN74LVC2G14DBV

5. TS5A23157DGSR

6. TPD4S012DRYR

7. MAX3221MDBREP

8. TXB0104RUTR

9. LMV339M

10. SN74LVC1G11IDCKRQ1

11. ULN2803ADWR

12. TPD4S009DBVR

13. LM239AMDREP

14. SM320F28335PTPMEP

15. LM2673SD-5.0/NOPBTR-ND

16. LM2673SD-3.3/NOPBTR-ND

I have attached excel sheet for your reference.

  • Hello,

    It would be best, and you would get the best support if you separated these requests into different threads, as different teams support different devices on this list.
    To help reduce the number of threads that you would need to post, I can tell you that my team supports part numbers 1,2,3,4,8,10, and I will provide information on these parts below.
    I can also help you pair some of the other parts on your list.
    Parts 6 and 12 go together
    Parts 9 and 13 go together
    Parts 15 and 16 go together
    5, 7, 11, and 14 are supported by different teams, so would be best to post new threads with each of these to get the appropriate support, but I can also help with parts 5 and 11 to help reduce the number of posts further.

    1. SN74LVC1G08QDBVRQ1 - 32mA MAX load - 1V maximum dropout - this is worst case, and it is only a single channel logic device so power consumption will be relatively minimal - If TA is observed, maximum Tj will not be reached. The power consumption of this device also depends on the load it is driving, so with a high impedance load this device will be dissipating little to no power.

    2. SN74LVC1G74DCTR - 32mA MAX load - 1V maximum dropout - this is worst case, and it is only a single channel logic device so power consumption will be relatively minimal - If TA is observed, maximum Tj will not be reached. The power consumption of this device also depends on the load it is driving, so with a high impedance load this device will be dissipating little to no power.

    3. SN74LVC1G32QDBVRQ1 - 32mA MAX load - 1V maximum dropout - this is worst case, and it is only a single channel logic device so power consumption will be relatively minimal - If TA is observed, maximum Tj will not be reached. The power consumption of this device also depends on the load it is driving, so with a high impedance load this device will be dissipating little to no power.

    4. SN74LVC2G14DBV - 32mA MAX load - 0.7V maximum dropout - 2 channels this is worst case, and it is only a dual channel logic device so power consumption will be relatively minimal - If TA is observed, maximum Tj will not be reached. The power consumption of this device also depends on the load it is driving, so with a high impedance load this device will be dissipating little to no power.

    5. TS5A23157DGSR - Maximum resistance is 10Ohms and maximum rated current is 50mA with two channels, so power dissipation can be calculated.

    8. TXB0104RUTR - 20uA MAX load - 0.4V maximum dropout - this is worst case, power consumption will be very little since this device cannot drive high currents. If TA is observed, maximum Tj will not be reached.

    10. SN74LVC1G11IDCKRQ1 - 32mA MAX load - 0.7V maximum dropout - this is worst case, and it is only a single channel logic device so power consumption will be relatively minimal - If TA is observed, maximum Tj will not be reached. The power consumption of this device also depends on the load it is driving, so with a high impedance load this device will be dissipating little to no power.

    11. ULN2803ADWR - This device does not have a rated maximum power consumption as the device can tolerate high current and high voltage. The key with this device is to understand that the ambient temperature and maximum junction temperature specifications are met, because with 8 channels sinking up to 500mA maximum and the VOL level specified in the datasheet, the device can reach maximum junction temperature easily.

    Best,
