Timing Waveform of Read Cycle for Pipelined Operation
NOTES:
1. OE is asynchronously controlled; all other inputs are synchronous to the rising clock edge.
2. ADS = V
3. The output is disabled (High-Impedance state) by CE
4. Addresses do not have to be accessed sequentially since ADS = V
5. If BE
Timing Waveform of a Multi-Device Pipelined Read
NOTES:
1. B1 Represents Device #1; B2 Represents Device #2. Each Device consists of one IDT70V3579 for this waveform,
2. BE
