Notes:

See

Figure 14, “AC Input/Output Reference Waveform” on page 48 for timing measurements and max

allowable input slew rate.

OE# may be delayed by up to tELQV – tGLQV after CE#’s falling edge without impact to tELQV.

Sampled, not 100% tested.

Address hold in synchronous burst read mode is tCHAX or tVHAX, whichever timing specification is satisfied first.

Synchronous burst read mode is not supported with TTL level inputs.

Applies only to subsequent synchronous reads.
