General Description

The 74HC595 is an 8-bit serial-in/serial-out or parallel-out shift register with 3-state outputs designed for 2.0V to 5.5V VCC operation.

The device integrates an 8-bit shift register and an 8-bit D-type storage register.

The storage register

Key Features

  • parallel 3-state outputs. The shift register provides a clear input (S.
  • R.
  • C.
  • L.
  • R.
  • ) with direct overriding function, a serial input (SER) and a serial output (QH') to implement cascading. When output enable input (O.
  • E.
  • ) is held low, the data in storage register will appear at the outputs. When O.
  • E.
  • is held high, all parallel outputs are in high-impedance state. Both the shift register and storage register hav.
