11 AC CHARACTERISTICS
VSS =0V; VDD = 2.5 to 6 V; VLCD =VDD 2.5 to VDD 6 V; Tamb = 40 to +85 °C; unless otherwise specied; note 1.
Notes
1. All timing values referred to VIH and VIL levels with an input voltage swing of VSS to VDD.
2. At fCLK < 125 kHz, I2C-bus maximum transmission speed is derated.
