It features separate shift and storage register clocks, serial input (DS) and serial output (Q7S) for cascading, asynchronous master reset (MR), and 100MHz typical shift-out frequency. Supply voltage range 2.0V to 6.0V, CMOS low power dissipation, specified from -40\u00b0C to +125\u00b0C.","working_principle":"Working Principle(Within 200 Words)","pin_description":"\n\n\n
