2.5 Operating speed
2.5.1
The speed of the devices is not highly dependent upon the supply voltage. However, by limiting the temperature
range, the speed can be increased. The minimal guaranteed speed as a function of the supply voltage and
maximal temperature operating temperature is given in Figure 2-5.
Figure 2-5. Guaranteed speed as a function of the supply voltage and maximal temperature.
2.5.2
2.5.2.1
In the low power supply configuration as shown in Figure 2-2, the operating speed does not depend highly on the
supply voltage as shown in Figure 2-6.

voltage regulator.
2.5.2.2
In the high speed supply configuration of Figure 2-3, the guaranteed speed of the circuit is shown in Figure 2-7.
