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 UB or LB was HIGH, then the appropriate Byte of DATA
Timing Waveform of a Multi-Device Pipelined Read
NOTES:
1. B1 Represents Device #1; B2 Represents Device #2. Each Device consists of one IDT70V3379 for this waveform,
2. UB, LB, OE, and ADS = V
