Notes: 1. This parameter is ensured by characterization and is not 100% tested.
2. AC measurement conditions:
 R_L (connects to V_CC): 1.3kΩ (2.5V, 5.5V), 10kΩ (1.7V)
 Input pulse voltages: 0.3V_CC to 0.7V_CC
 Input rise and fall times: ≤ 50ns
 Input and output timing reference voltages: 0.5 x V_CC
