DESCRIPTION
The M54/74HC166 is a high speed C
2
MOS 8 BIT
PISO SHIFT REGISTER fabricated in silicon gate
C
2
MOStechnology.Ithas thesame highspeedper-
formance of LSTTL combined with true CMOS low
powerconsumption.
It consistsof 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.
WhentheSHIFT/LOAD inputis held high, the serial
data input isenabled andtheeightflip-flopsperform
serialshifting with each clock pulse. When heldlow,
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
CLOCKinput 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 truthtable and the timing chart.
All inputs are equipped with protection circuits
against static discharge and transient excess volt-
age.
