2. Measured as HIGH above V
3. This parameter is measured with the output loading shown in Figure 2 unless otherwise noted.
4. This parameter is sampled.
5. Transition is measured ±500mV from steady state voltage.
6. Refer to Technical Note TN-58-09, “Synchronous SRAM Bus Contention Design Considerations,” for a more thorough
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 times.
9. This is a synchronous device. All addresses must meet the specified setup and hold times for all rising edges of CLK
discussion on these parameters.
A READ cycle is defined by all byte write enables HIGH and ADSC# or ADV# LOW or ADSP# LOW for the required setup
and hold times.
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.
