SN74ALVTH16245: Theta JC (Junction to Case)

K.Yaita

Part Number: SN74ALVTH16245

Hi Team,

Could you tell me the value of Theta JC (Junction to Case) for the following?

・SN74ALVTH16245GR
・CDCV304PW
・SN74LVC2T45DCU
・SN74LVC541APW

I would also like to ask Tj-max for these.

Best Regards,
Yaita

Hi Yaita san ,

The abs max Tj is 150C beyond which there might be damage and reliability issues with the device .

SN74ALVTH16245GR - I will have to submit thermal request to get you but the theta JC values of others are given in the datasheet. Please let me know if you need anything else.

Hi ShreyasRao-san,

Thank you for your support.

I aplogies other logic ICs have JC values in datasheet.. I overlooked these.
I will wait for your reply for SN74ALVTH16245GR.

Best Regards,
Yaita
