Read Timing
Notes:
*1. Q(A2) refers to output from address A2. Q(A2+1) refers to output from the internal burst address immediately
following A2.
*2. Timing for
CE2
and CE2 is identical to that for
CE
. As shown in this diagram, when
CE
is LOW,
CE2
is
LOW and CE2 is HIGH. When
CE
is HIGH,
CE2
is HIGH and CE2 is LOW.
*3. Timing shown assumes that the device was not enabled before entering this sequence.
OE
does not cause Q to
be driven until after the rising edge of the following clock.
