3. This parameter is measured with the output loading shown in Figure 2.
4. This parameter is sampled.
5. Transition is measured ±500mV from steady state voltage.

7. OE# is a “Don’t Care” when a byte write enable is sampled LOW.
8. A WRITE cycle is defined by at least one byte write enable LOW and ADSP# HIGH for the required setup and hold

when either ADSP# or ADSC# is LOW and chip enabled. All other synchronous inputs must meet the setup and hold
times with stable logic levels for all rising edges of clock (CLK) when the chip is enabled. Chip enable must be valid at
each rising edge of CLK when either ADSP# or ADSC# is LOW to remain enabled.
