Product specification
5-Bit x 64-word FIFO register; 3-state
74HC/HCT7404
Shift-out operation; high-speed burst mode
Note to
Fig.13
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 an SO pulse can be applied without regard to the flag.
Fig.13 Waveforms showing SO minimum pulse width and maximum pulse frequency, in high-speed shift-out
burst mode.
