Commercial and Industrial Temperature Ranges
Timing Waveform of Read Cycle No. 2(1)
NOTES:
1. A write occurs during the overlap of a LOW CS, LOW BHE or BLE, and a LOW WE.
2. OE is continuously HIGH. If during a WE controlled write cycle OE is LOW, tWP must be greater than or equal to tWHZ+ tDW to allow the I/O drivers to turn off and data to be placed
on the bus for the required tDW. If OE is HIGH during a WE controlled write cycle, this requirement does not apply and the minimum write pulse is as short as the specified tWP.
3. During this period, I/O pins are in the output state, and input signals must not be applied.
4. IftheCS LOWorBHEand BLE LOWtransitionoccurssimultaneouslywithorafterthe WELOWtransition,theoutputsremaininahigh-impedancestate.
5. Transitionismeasured±200mVfromsteadystate.
Timing Waveform of Write Cycle No. 1 (WE Controlled Timing)(1,2,4)
NOTES:
1. WE is HIGH for Read Cycle.
2. Address must be valid prior to or coincident with the later of CS, BHE, or BLE transition LOW; otherwise tAA is the limiting parameter.
3. Transitionismeasured±200mVfromsteadystate.
