(V
DD
= 2.5V ± 100mV, T
A
= 0°C to +70°C)
NOTES:
1. The Pipelined output parameters (t
CYC2
, t
CD2
) apply to either or both left and right ports when
FT
/PIPE
X
= V
DD
(2.5V). Flow-through parameters (t
CYC1
, t
CD1
)
apply when
FT
/PIPE = V
ss
(0V) for that port.
2. All input signals are synchronous with respect to the clock except for the asynchronous Output Enable (
OE
),
FT
/PIPE and OPT.
FT
/PIPE and OPT should be
treated as DC signals, i.e. steady state during operation.
3. These values are valid for either level of V
DDQ
(3.3V/2.5V). See page 6 for details on selecting the desired operating voltage levels for each port.
4. Guaranteed by design (not production tested).
