In normal steady-state operation when V
the output will be at a logic-high (see Figure 3-1). In
the case of the TC54VN, this is an open-drain
condition. If the input falls below V
will pull down (Logic 0) to V
pull down to within 0.5V of V
and input voltage. (See Section 1.0 “Electrical
Characteristics”).
