8 / 15 page PRELIMINARY KM736V689/L 64Kx36 Synchronous SRAM - 8 - Rev 1.0 April 1997 AC TIMING CHARACTERISTICS NOTE : 1. All address inputs must meet the specified setup and hold times for all rising clock edges whenever ADSC and/or ADSP is sampled low and CS is sampled low. All other synchronous inputs must meet the specified setup and hold times whenever this device is chip selected. 2. Both chip selects must be active whenever ADSC or ADSP is sampled low in order for the this device to remain enabled. 3. ADSC or ADSP must not be asserted for at least 2 Clock after leaving ZZ state.
