NOTES:
1. “Write” applies to the SW signal. “Enable” applies to SE0, SE1, and DE signals.
2. All read and write cycle timings are referenced from K or G.
3. G is a don’t care after write cycle begins. To prevent bus contention, G should be negated prior to start of write cycle.
4. Tested per AC Test Load (See Figure 1).
5. This parameter is sampled and not 100% tested.
6. Measured at ± 200 mV from steady state.
