Figure 6. Read Cycle for Flow-Through Output (FT/PIPE = V
IL
) [16, 17, 18, 19]
Notes
16. OE is asynchronously controlled; all other inputs are synchronous to the rising clock edge.
17. ADS = V
IL
, CNTEN and CNTRST = V
IH
.
18. The output is disabled (high-impedance state) by CE
0
=V
IH
or CE
1
= V
IL
following the next rising edge of the clock.
19. Addresses do not have to be accessed sequentially since ADS = V
IL
constantly loads the address on the rising edge of the CLK. Numbers are for reference
only.
