1.2 Read Mode
(See Timing Diagrams and AC Characteristics)
Read Mode is accessed when
a) the CE pin is low to power up (enable) the chip
b) the OE pin is low to gate the data to the output
pins
For Read operations, if the addresses are stable, the
address access time (tACC) is equal to the delay from
CE to output (tCE). Data is transferred to the output
after a delay from the falling edge of OE (tOE).
