The storage register has parallel 3state outputs. Separate clocks are provided for both the shift register 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 all outputs are in the high-impedance state except QH'. Table 1.
