3 Description
The SN74AC595 contains an 8-bit serial-in, parallelout
shift register that feeds an 8-bit D-type storage
register. This configuration allows data to be loaded
into the shift register while the outputs remain static.
The device includes 3-state outputs to allow for
disabling the outputs. The device has a separate shift
register output (QH') for connecting shift registers in
series.
