Notes:
1. Applicable over recommended operating range from TA = 0°C to +70°C, VCC = +2.7V to +5.5V, CL = 100 pF (unless other-
wise noted). Test conditions are listed in Note 3.
2. This parameter is characterized and is not 100% tested.
3. AC measurement conditions:
RL (connects to VCC): 1.3 kΩ (2.7V, 5V),
Input pulse voltages: 0.3VCC to 0.7VCC
Input rise and fall times: ≤ 50ns
Input and output timing reference voltages: 0.5VCC
