CONTROL PIN CHARACTERISTICS (Cont’d)
12.9.2 ICCSEL/V
Subject to general operating conditions for V
Figure 109. Two typical Applications with ICCSEL/V
Notes:
1. Data based on design simulation and/or technology characteristics, not tested in production.
2. When ICC mode is not required by the application ICCSEL/V
