1. This parameter is characterized and is not 100% tested.
2. AC measurement conditions:
RL (connects to VCC): 1.3 k
Input pulse voltages: 0.3 VCC to 0.7 VCC
Input rise and fall time: 50 ns
Input and output timing reference voltages: 0.5 VCC
The value of RL should be concerned according to the actual loading on the user's system.
