SN74ACT32: Thermal Characteristics

Jesus Martinez

Part Number: SN74ACT32

Hi My name is Jesus Martinez and I am a Thermal Analyst for L3Harris. We are using this component on one of our designs and I am looking for the following information:

Maximum Operating Junction Temp: °C

Junction to Board Thermal Resistance: °C/W

Junction to Top Thermal Resistance: °C/W

Thanks,

Hi Jesus,

Do you have the specific package and part number for the device you want this information for? I will have to send in a request to get the information for "Junction to Board" and "Junction to Top". This report will have a turn around time of about two weeks.

In the meantime, for Junction Temp, you can refer to this FAQ: [FAQ] What is the maximum junction temperature (TJMAX) for a device?
