1. This parameter is characterized and is not 100% tested.

2. AC measurement conditions:

RL (

connects to VCC): 1.3 k (2.5V, 5V), 10 k (1.8V)

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.
