DESCRIPTION
The M54/74HC166 is a high speed C2MOS 8 BIT
PISO SHIFT REGISTER fabricated in silicon gate
C2MOS technology. It has the same high speed performance of LSTTL combined with true CMOS low
power consumption.
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.

(*) 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 operting current can be obtained by the following equation. ICC(opr) = CPD •VCC •fIN + ICC
