11 I
All timing values are valid within the operating supply voltage and ambient temperature range and refer to V
with an input voltage swing from V
Note
1. The hold time required (not greater than 300 ns) to bridge the undefined region of the falling edge of SCL must be
12 WRITE CYCLE LIMITS
Selection of the chip address is achieved by connecting the A0, A1 and A2 inputs to either V
