8.1 Minimizing I
When the I/Os are used to control LEDs, they are normally connected to V
resistor as shown in
V
than V
Designs needing to minimize current consumption, such as battery power applications,
should consider maintaining the I/O pins greater than or equal to V
Figure 17
than the LED supply voltage by at least 1.2 V. Both of these methods maintain the I/O V
or above V
Table 13.
In accordance with the Absolute Maximum Rating System (IEC 60134).
