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.
