Conditions

Note 1: The TC72-2.8MXX, TC72-3.3MXX and TC72-5.0MXX will operate from a supply voltage of 2.65V to 5.5V. However, the

TC72-2.8MXX, TC72-3.3MXX and TC72-5.0MXX are tested and specified at the nominal operating voltages of 2.8V,

Figure 2-5 and Figure 2-6.

3: All time measurements are measured with respect to the 50% point of the signal, except for the SCK rise and fall times.

The rise and fall times are defined as the 10% to 90% transition time.
