Notes:
1. X means “don’t care,” H means “l(fā)ogic high,” L means “l(fā)ogic low.”
2. Write is the logic function of GW, BWE, BW1, BW2. See Byte Write Function table for detail.
3. CE is defined as CE1=L, CE2=H and CE3=L
4. All signals are synchronous and are sampled by CLK except OE and MOE. OE and MOE are asynchronous and drive the bus immediately.
Note:
Permanent damage to the device may occur if the Absolute Maximun Ratings are exceeded. Functional operation should be restricted to the
recommended operation conditions. Exposure to higher than recommended voltages, for an extended period of time, could effect the
performance and reliability of this component.
