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