CD4044B: Need Information about Power Dissipation

Sundar Raj A

Part Number: CD4044B

Tool/software:

Please share the junction temperature (Tj) and the thermal resistance from junction to ambient, RθJA. Additionally, could you provide any formulas or calculations related to power dissipation?

Hi Sundar,

Tj = 150C.

However, since these devices are so old, we do not have thermal resistance data. You do need this data to calculate power dissipation, however, the power dissipation is listed in the datasheet.

For an equation please refer to this FAQ: [FAQ] Where do I find maximum power dissipation for a device?
