Notes: *1 Input pulse level: 0.45 V to 2.4 V; input rise, fall times ≤ 20 ns; input timing reference
levels: 0.8 V, 2.0 V; output timing reference levels: 0.8 V, 2.0 V.
*2 t_DF is defined as when the output becomes open state and referencing the output level is
no longer possible.
*3 t_OPW is defined by the values noted in the flowchart (figure 21.6).
