NOTE1: This parameter is characterized and is not 100% tested.
NOTE2: AC measurement conditions: RL(connects to VCC): 1.3kΩ
Input pulse voltages: 0.3 VCC to 0.7VCC
Input rise and fall time: 50ns
Input and output timing reference voltages: 0.5VCC
The value of RL should be concerned according to the actual loading on the user’s system.
