DC parameters are guaranteed after thermal equilibrium has been established.
The LVL input determines the voltage switching threshold that differentiates logic high from logic low for the V
DELAY_SEL, and CINV. LVL may be driven to V
logic high. Also, as shown in Figure 3, the LVL input internally clamps at V
