SN65HVD33-EP: How do we calculate the power consumption of this driver??

Part Number: SN65HVD33-EP

we are working on a project which uses 20- SN65HVD33 ICs, so we need to calculate the power consumption of this IC. Can anyone help us with this.

    Power can be estimated by looking at a couple pieces of data in the datasheet.

    First, there is the Pd rating in section 7.10.  For the HVD33 at 25Mbps, this is a max of 197mW (3.3V, 85c with 60ohm load)

    Additionally, Figure 1 shows how this scales with respect to signal rate.   If your rate is slower, you can derate the 197mW based on slope of figure 1.
