Philips Semiconductors
Shift-out operation; high-speed burst mode
December 1990
9-bit x 64-word FIFO register; 3-state
In the high-speed mode, the burst-out rate is determined by the minimum shift-out HIGH and shift-out LOW
specifications. The DOR flag is a don’t care condition and a SO pulse can be applied without regard to the flag.
