The SN74HCS595 device contains an 8-bit, serial-in, parallel-out shift register that feeds an 8-bit D-type storage register. All inputs include Schmitt-trigger architecture, eliminating any erroneous data outputs due to slow-edged or noisy input signals. 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 a serial output (Q_H’) for cascading. When the output-enable (OE) input is high, the storage register outputs are in a high-impedance state. Internal register data and serial output (Q_H’) are not impacted by the operation of the OE input.
