Notes:
1. These parameters are determined through product characterization and are not 100% tested in production.
2. AC measurement conditions:
CL : 100pF
RPUP (SDA bus line pull-up resistor to VCC): 1.3k (1000kHz), 4k (400kHz), 10k (100kHz)
Input pulse voltages: 0.3 x VCC to 0.7 x VCC
Input rise and fall times: 50ns
Input and output timing reference voltages: 0.5 x VCC
