DESCRIPTION

The M54/74HC166 is a high speed C²MOS 8 BIT

PISO SHIFT REGISTER fabricated in silicon gate

C²MOS technology. It has the same highspeed per-

formance 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 syn-

chronous 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 over-

rides 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.

NC =

No Inter-

nal Con-

All inputs are equipped with protection circuits

against static discharge and transient excess volt-

age.
