1.5V to 6V, eight-bit shift registers with tri-state output registers

The SN74AC595 contains an 8-bit serial-in, parallel-out 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.
