Notes: 1. CE may be delayed up to tACC - tCE after the address
transition without impact on tACC
3. tDF is specified from OE or CE whichever occurs first
(CL = 5 pF).

2. OE may be delayed up to tCE - tOE after the falling
edge of CE without impact on tCE or by tACC - tOE

Note: While CE is active, any address inputs that cause VIH to drop
below 2.0V or VIL to rise above 0.8V for a duration of up to 15 ns
may cause the device to read incorrectly.
