SN74AUC125: sn74auc125rgy thermal information

Harrison Citrin

Part Number: SN74AUC125

Hello,

For part sn74auc125rgy, can you please provide the recommended operating junction temperature range and the absolute maximum junction temperature? Can you also provide the junction-to-case thermal resistance (degC/W)?

Thank you.

Hi Harrison,

The absolute maximum junction temperature is 150C. [FAQ] What is the maximum junction temperature (TJMAX) for a device? - Logic forum - Logic - TI E2E support forums

For the operating junction temperature range as long as they are in between operating temperature in the datasheet and below the maximum junction temperature, then it should be fine.

Here are the standard datasheet thermal values for that part.

Result- Theta JA-High K (standard datasheet value)	60.8
Result-Theta JC, top (standard datasheet value)	58.7
Result-Theta JB (standard datasheet value)	34.9
Result- Psi JT (standard datasheet value)	4.4
Result- Psi JB (standard datasheet value)	35.0
Result-Theta JC, bottom (standard datasheet value)	16.4

Thanks!
