Texas Instruments SN74AC595/SN74AC595-Q1 8-Bit Shift Registers include an 8-bit serial-in, parallel-out shift register that provides an 8-bit D-type storage register. This configuration allows data to be loaded into the shift register while the outputs remain static. The TI SN74AC595/SN74AC595-Q1 features 3-state outputs to facilitate the disabling of the outputs.
