Notes: 1. Input pulse level: 0.8 V to 2.2 V

Input rise time and fall time

≤ 20 ns

Timing reference levels; Input: 1.0 V, 2.0 V;

Output: 0.8 V, 2.0 V

2. t

DF is defined to be when output has reached the open state, and the output level can no

longer be referenced.

3. t

OPW is defined by the value shown in the flowchart.
