3 Description
The SNx4AHC594 devices contain an 8-bit serial-in,
parallel-out shift register that feeds an 8-bit D-type
storage register. Separate clocks and direct
overriding clear (SRCLR, RCLR) inputs are provided
on the shift and storage registers. A serial (QH)
output is provided for cascading purposes.
