Operation modes
If the address inputs are changed while E and G remain active, output data will remain valid
for output data hold time (tAXQX) but will go indeterminate until the next address access.

1. Valid for ambient operating temperature: TA = 0 to 70 or –40 to 85 °C; VCC = 4.75 to 5.5 V or 4.5 to 5.5 V (except where
noted).
2. CL = 5 pF.
