Notes:

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.
