Note:

Make sure that Tj = Ta + θja × total power consumption (W), where total power consumption = (VCC - VOH) × ΣIOH + VOL × ΣIOL +

ICCmax × VCC.

Note 1. The upper limit of operating temperature is 125 °C, depending on the product. If the part number shows the operation temperature

at 105 °C, then the maximum value of Tj is 125 °C.
