The SN74HC595BRWNR devices contain an 8-bit, serial-in, parallel-out shift register that feeds an 8-bit D-type storage register. The storage register has parallel 3-state outputs. Separate clocks are provided for both the shift register and storage register. The shift register has a direct overriding clear (OE) input is high, the all outputs are in the high-impedance state except QH’.
