DESCRIPTION The M74HC166 is an high speed CMOS 8 BIT PISO SHIFT REGISTER fabricated with silicon gate C2MOS technology. It consists of parallel or serial inputs and a serial-out 8 bit shift register with gated clock inputs and an overriding clear input. The parallel-in or serial-in modes are controlled by the SHIFT/ LOAD input. When the SHIFT/LOAD input is held high, the serial data input is enabled and the eight flip-flops perform serial shifting with each clock pulse; when held low, the parallel data inputs are
enabled and synchronous loading occurs on the next clock pulse. Clocking is accomplished on the low-to-high level edge of the clock pulse. The CLOCK-INHIBIT input should be changed to the high only while the clock input is held high. A direct clear input overrides all other inputs, including the clock, and sets all flip-flops to zero. Functional details are shown in the truth table and the timing chart. All inputs are equipped with protection circuits against static discharge and transient excess voltage.

CIN CPD
Input Capacitance Power Dissipation Capacitance (note 1)
1) CPD is defined as the value of the IC's internal equivalent capacitance which is calculated from the operating current consumption without load. (Refer to Test Circuit). Average operating current can be obtained by the following equation. ICC(opr) = CPD x VCC x fIN + ICC
