Specifications of 72V263L15PF

• Part # Aliases: IDT72V263L15PF

NOTES:
1. If the part is empty at the point of Retransmit, the Empty Flag (EF) will be updated based on RCLK (Retransmit clock cycle). Valid data will also appear on the output.
2. OE = LOW: enables data to be read on outputs Q
3. W
4. No more than D - 2 may be written to the FIFO between Reset (Master or Partial) and Retransmit setup. Therefore, FF will be HIGH throughout the Retransmit setup procedure.
5. There must be at least two words written to and read from the FIFO before a Retransmit operation can be invoked.
6. RM is set LOW during MRS.
