AC Characteristics
Test Conditions
• Input pules levels:
 V_IL = V_CC × 0.2
 V_IH = V_CC × 0.8
• Input rise and fall time: ≤ 10 ns
• Input and output timing reference levels: V_CC × 0.3, V_CC × 0.7
• Output reference levels: V_CC × 0.5
• Output load: 100 pF
(Ta = −40 to +85°C, V_CC = 2.5 V to 5.5 V)
