IDT72V3656 IDT [Integrated Device Technology], IDT72V3656 Datasheet - Page 36

• Manufacturer Part Number: IDT72V3656
• Description: 3.3 VOLT CMOS TRIPLE BUS SyncFIFOTM WITH BUS-MATCHING
• Manufacturer: IDT [Integrated Device Technology]

NOTES:
1. CSA = LOW
2. Retransmit setup is complete after ORA returns HIGH, only then can a read operation begin.
3. W1 = first word written to the FIFO2 after Master Reset on FIFO2.
4. No more than D-2 may be written to the FIFO2 between Reset of FIFO2 (Master or Partial) and Retransmit setup. Therefore, IRC will be LOW throughout the Retransmit
NOTES:
1. CSB = LOW
2. Retransmit setup is complete after ORB returns HIGH, only then can a read operation begin.
3. W1 = first word written to the FIFO1 after Master Reset on FIFO1.
4. No more than D-2 may be written to the FIFO1 between Reset of FIFO1 (Master or Partial) and Retransmit setup. Therefore, IRA will be LOW throughout the Retransmit
