† Notice: Stresses above those listed under "Maximum

Ratings" may cause permanent damage to the device. This is

a stress rating only and functional operation of the device at

those or any other conditions above those indicated in the

operation listings of this specification is not implied. Exposure

to maximum rating conditions for extended periods may affect

device reliability.

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.
