SN74HC595N Datasheet PDF - TI

The SN74HC595N device 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 and storage register. The shift register has a direct overriding clear (SRCLR) input, serial (SER) input, and serial outputs for cascading. When the output-enable (OE) input is high, the outputs are in the high-impedance state. Both the shift register clock (SRCLK) and storage register clock (RCLK) are positive-edge triggered. If both clocks are connected together, the shift register always is one clock pulse ahead of the storage register.
